Thorlabs' premium bandpass filters, which are designed to provide enhanced isolation of key Yb:YAG, Nd:YLF, Nd:YAG, HeNe, Ar, and diode laser lines, offer excellent (ODavg ≥4) suppression in the blocking region while providing ≥85% transmission at the design wavelength (except the 300 nm filter which offers ≥50% transmission). The pass bands of these filters range from 4 to 40 nm FWHM, depending on the center wavelength chosen, with steep cut-on and cut-off slopes.

Our premium bandpass filters are available with 12.5 mm or 25 mm outer diameters. The filters are 3.5 mm thick, which allows the Ø25 mm filters to be used as drop-in replacements for our fluorescence emission filters.

These bandpass filters feature durable, hard-coated dielectric coatings on a UV fused silica substrate. The film construction is essentially a modified quarter-wave stack, using interference effects to isolate spectral bands. The coating is more dense than those on our standard bandpass filters, allowing them to be constructed using a single substrate, and yields a more stable, longer-lasting filter. The coating on these filters can withstand the normal cleaning and handling necessary when using any high-quality optical component.

Each filter is housed in a black anodized aluminum ring that is labeled with an arrow indicating the design propagation direction. The ring makes handling easier and enhances the blocking OD by limiting scattering. These filters can be mounted in our extensive line of filter mounts and wheels. As the mounts are not threaded, retaining rings will be required to mount the filters in one of our internally threaded lens tubes. We do not recommend removing the filter from its mount as the risk of damaging the filter is very high.

Laser Induced Damage Threshold Tutorial

The following is a general overview of how laser induced damage thresholds are measured and how the values may be utilized in determining the appropriateness of an optic for a given application. When choosing optics, it is important to understand the Laser Induced Damage Threshold (LIDT) of the optics being used. The LIDT for an optic greatly depends on the type of laser you are using. Continuous wave (CW) lasers typically cause damage from thermal effects (absorption either in the coating or in the substrate). Pulsed lasers, on the other hand, often strip electrons from the lattice structure of an optic before causing thermal damage. Note that the guideline presented here assumes room temperature operation and optics in new condition (i.e., within scratch-dig spec, surface free of contamination, etc.). Because dust or other particles on the surface of an optic can cause damage at lower thresholds, we recommend keeping surfaces clean and free of debris. For more information on cleaning optics, please see our Optics Cleaning tutorial.

Testing Method

Thorlabs' LIDT testing is done in compliance with ISO/DIS 11254 and ISO 21254 specifications.

First, a low-power/energy beam is directed to the optic under test. The optic is exposed in 10 locations to this laser beam for 30 seconds (CW) or for a number of pulses (pulse repetition frequency specified). After exposure, the optic is examined by a microscope (~100X magnification) for any visible damage. The number of locations that are damaged at a particular power/energy level is recorded. Next, the power/energy is either increased or decreased and the optic is exposed at 10 new locations. This process is repeated until damage is observed. The damage threshold is then assigned to be the highest power/energy that the optic can withstand without causing damage. A histogram such as that below represents the testing of one BB1-E02 mirror.

LIDT metallic mirror
The photograph above is a protected aluminum-coated mirror after LIDT testing. In this particular test, it handled 0.43 J/cm2 (1064 nm, 10 ns pulse, 10 Hz, Ø1.000 mm) before damage.
LIDT BB1-E02
Example Test Data
Fluence # of Tested Locations Locations with Damage Locations Without Damage
1.50 J/cm2 10 0 10
1.75 J/cm2 10 0 10
2.00 J/cm2 10 0 10
2.25 J/cm2 10 1 9
3.00 J/cm2 10 1 9
5.00 J/cm2 10 9 1

According to the test, the damage threshold of the mirror was 2.00 J/cm2 (532 nm, 10 ns pulse, 10 Hz, Ø0.803 mm). Please keep in mind that these tests are performed on clean optics, as dirt and contamination can significantly lower the damage threshold of a component. While the test results are only representative of one coating run, Thorlabs specifies damage threshold values that account for coating variances.

Continuous Wave and Long-Pulse Lasers

When an optic is damaged by a continuous wave (CW) laser, it is usually due to the melting of the surface as a result of absorbing the laser's energy or damage to the optical coating (antireflection) [1]. Pulsed lasers with pulse lengths longer than 1 µs can be treated as CW lasers for LIDT discussions.

When pulse lengths are between 1 ns and 1 µs, laser-induced damage can occur either because of absorption or a dielectric breakdown (therefore, a user must check both CW and pulsed LIDT). Absorption is either due to an intrinsic property of the optic or due to surface irregularities; thus LIDT values are only valid for optics meeting or exceeding the surface quality specifications given by a manufacturer. While many optics can handle high power CW lasers, cemented (e.g., achromatic doublets) or highly absorptive (e.g., ND filters) optics tend to have lower CW damage thresholds. These lower thresholds are due to absorption or scattering in the cement or metal coating.

Linear Power Density Scaling

LIDT in linear power density vs. pulse length and spot size. For long pulses to CW, linear power density becomes a constant with spot size. This graph was obtained from [1].

Intensity Distribution

Pulsed lasers with high pulse repetition frequencies (PRF) may behave similarly to CW beams. Unfortunately, this is highly dependent on factors such as absorption and thermal diffusivity, so there is no reliable method for determining when a high PRF laser will damage an optic due to thermal effects. For beams with a high PRF both the average and peak powers must be compared to the equivalent CW power. Additionally, for highly transparent materials, there is little to no drop in the LIDT with increasing PRF.

In order to use the specified CW damage threshold of an optic, it is necessary to know the following:

  1. Wavelength of your laser
  2. Beam diameter of your beam (1/e2)
  3. Approximate intensity profile of your beam (e.g., Gaussian)
  4. Linear power density of your beam (total power divided by 1/e2 beam diameter)

Thorlabs expresses LIDT for CW lasers as a linear power density measured in W/cm. In this regime, the LIDT given as a linear power density can be applied to any beam diameter; one does not need to compute an adjusted LIDT to adjust for changes in spot size, as demonstrated by the graph to the right. Average linear power density can be calculated using the equation below. 

The calculation above assumes a uniform beam intensity profile. You must now consider hotspots in the beam or other non-uniform intensity profiles and roughly calculate a maximum power density. For reference, a Gaussian beam typically has a maximum power density that is twice that of the uniform beam (see lower right).

Now compare the maximum power density to that which is specified as the LIDT for the optic. If the optic was tested at a wavelength other than your operating wavelength, the damage threshold must be scaled appropriately. A good rule of thumb is that the damage threshold has a linear relationship with wavelength such that as you move to shorter wavelengths, the damage threshold decreases (i.e., a LIDT of 10 W/cm at 1310 nm scales to 5 W/cm at 655 nm):

CW Wavelength Scaling

While this rule of thumb provides a general trend, it is not a quantitative analysis of LIDT vs wavelength. In CW applications, for instance, damage scales more strongly with absorption in the coating and substrate, which does not necessarily scale well with wavelength. While the above procedure provides a good rule of thumb for LIDT values, please contact Tech Support if your wavelength is different from the specified LIDT wavelength. If your power density is less than the adjusted LIDT of the optic, then the optic should work for your application. 

Please note that we have a buffer built in between the specified damage thresholds online and the tests which we have done, which accommodates variation between batches. Upon request, we can provide individual test information and a testing certificate. The damage analysis will be carried out on a similar optic (customer's optic will not be damaged). Testing may result in additional costs or lead times. Contact Tech Support for more information.

Pulsed Lasers

As previously stated, pulsed lasers typically induce a different type of damage to the optic than CW lasers. Pulsed lasers often do not heat the optic enough to damage it; instead, pulsed lasers produce strong electric fields capable of inducing dielectric breakdown in the material. Unfortunately, it can be very difficult to compare the LIDT specification of an optic to your laser. There are multiple regimes in which a pulsed laser can damage an optic and this is based on the laser's pulse length. The highlighted columns in the table below outline the relevant pulse lengths for our specified LIDT values.

Pulses shorter than 10-9 s cannot be compared to our specified LIDT values with much reliability. In this ultra-short-pulse regime various mechanics, such as multiphoton-avalanche ionization, take over as the predominate damage mechanism [2]. In contrast, pulses between 10-7 s and 10-4 s may cause damage to an optic either because of dielectric breakdown or thermal effects. This means that both CW and pulsed damage thresholds must be compared to the laser beam to determine whether the optic is suitable for your application.

Pulse Duration t < 10-9 s 10-9 < t < 10-7 s 10-7 < t < 10-4 s t > 10-4 s
Damage Mechanism Avalanche Ionization Dielectric Breakdown Dielectric Breakdown or Thermal Thermal
Relevant Damage Specification No Comparison (See Above) Pulsed Pulsed and CW CW

When comparing an LIDT specified for a pulsed laser to your laser, it is essential to know the following:

Energy Density Scaling

LIDT in energy density vs. pulse length and spot size. For short pulses, energy density becomes a constant with spot size. This graph was obtained from [1].

  1. Wavelength of your laser
  2. Energy density of your beam (total energy divided by 1/e2 area)
  3. Pulse length of your laser
  4. Pulse repetition frequency (prf) of your laser
  5. Beam diameter of your laser (1/e2 )
  6. Approximate intensity profile of your beam (e.g., Gaussian)

The energy density of your beam should be calculated in terms of J/cm2. The graph to the right shows why expressing the LIDT as an energy density provides the best metric for short pulse sources. In this regime, the LIDT given as an energy density can be applied to any beam diameter; one does not need to compute an adjusted LIDT to adjust for changes in spot size. This calculation assumes a uniform beam intensity profile. You must now adjust this energy density to account for hotspots or other nonuniform intensity profiles and roughly calculate a maximum energy density. For reference a Gaussian beam typically has a maximum energy density that is twice that of the 1/e2 beam.

Now compare the maximum energy density to that which is specified as the LIDT for the optic. If the optic was tested at a wavelength other than your operating wavelength, the damage threshold must be scaled appropriately [3]. A good rule of thumb is that the damage threshold has an inverse square root relationship with wavelength such that as you move to shorter wavelengths, the damage threshold decreases (i.e., a LIDT of 1 J/cm2 at 1064 nm scales to 0.7 J/cm2 at 532 nm):

Pulse Wavelength Scaling

You now have a wavelength-adjusted energy density, which you will use in the following step.

Beam diameter is also important to know when comparing damage thresholds. While the LIDT, when expressed in units of J/cm², scales independently of spot size; large beam sizes are more likely to illuminate a larger number of defects which can lead to greater variances in the LIDT [4]. For data presented here, a <1 mm beam size was used to measure the LIDT. For beams sizes greater than 5 mm, the LIDT (J/cm2) will not scale independently of beam diameter due to the larger size beam exposing more defects.

The pulse length must now be compensated for. The longer the pulse duration, the more energy the optic can handle. For pulse widths between 1 - 100 ns, an approximation is as follows:

Pulse Length Scaling

Use this formula to calculate the Adjusted LIDT for an optic based on your pulse length. If your maximum energy density is less than this adjusted LIDT maximum energy density, then the optic should be suitable for your application. Keep in mind that this calculation is only used for pulses between 10-9 s and 10-7 s. For pulses between 10-7 s and 10-4 s, the CW LIDT must also be checked before deeming the optic appropriate for your application.

In order to illustrate the process of determining whether a given laser system will damage an optic, a number of example calculations of laser induced damage threshold are given below. For assistance with performing similar calculations, we provide a spreadsheet calculator that can be downloaded by clicking the button to the right. To use the calculator, enter the specified LIDT value of the optic under consideration and the relevant parameters of your laser system in the green boxes. The spreadsheet will then calculate a linear power density for CW and pulsed systems, as well as an energy density value for pulsed systems. These values are used to calculate adjusted, scaled LIDT values for the optics based on accepted scaling laws. This calculator assumes a Gaussian beam profile, so a correction factor must be introduced for other beam shapes (uniform, etc.). The LIDT scaling laws are determined from empirical relationships; their accuracy is not guaranteed. Remember that absorption by optics or coatings can significantly reduce LIDT in some spectral regions. These LIDT values are not valid for ultrashort pulses less than one nanosecond in duration.

Intensity Distribution
A Gaussian beam profile has about twice the maximum intensity of a uniform beam profile.

CW Laser Example
Suppose that a CW laser system at 1319 nm produces a 0.5 W Gaussian beam that has a 1/e2 diameter of 10 mm. A naive calculation of the average linear power density of this beam would yield a value of 0.5 W/cm, given by the total power divided by the beam diameter:

CW Wavelength Scaling

However, the maximum power density of a Gaussian beam is about twice the maximum power density of a uniform beam, as shown in the graph to the right. Therefore, a more accurate determination of the maximum linear power density of the system is 1 W/cm.

An AC127-030-C achromatic doublet lens has a specified CW LIDT of 350 W/cm, as tested at 1550 nm. CW damage threshold values typically scale directly with the wavelength of the laser source, so this yields an adjusted LIDT value:

CW Wavelength Scaling

The adjusted LIDT value of 350 W/cm x (1319 nm / 1550 nm) = 298 W/cm is significantly higher than the calculated maximum linear power density of the laser system, so it would be safe to use this doublet lens for this application.

Pulsed Nanosecond Laser Example: Scaling for Different Pulse Durations
Suppose that a pulsed Nd:YAG laser system is frequency tripled to produce a 10 Hz output, consisting of 2 ns output pulses at 355 nm, each with 1 J of energy, in a Gaussian beam with a 1.9 cm beam diameter (1/e2). The average energy density of each pulse is found by dividing the pulse energy by the beam area:

Pulse Energy Density

As described above, the maximum energy density of a Gaussian beam is about twice the average energy density. So, the maximum energy density of this beam is ~0.7 J/cm2.

The energy density of the beam can be compared to the LIDT values of 1 J/cm2 and 3.5 J/cm2 for a BB1-E01 broadband dielectric mirror and an NB1-K08 Nd:YAG laser line mirror, respectively. Both of these LIDT values, while measured at 355 nm, were determined with a 10 ns pulsed laser at 10 Hz. Therefore, an adjustment must be applied for the shorter pulse duration of the system under consideration. As described on the previous tab, LIDT values in the nanosecond pulse regime scale with the square root of the laser pulse duration:

Pulse Length Scaling

This adjustment factor results in LIDT values of 0.45 J/cm2 for the BB1-E01 broadband mirror and 1.6 J/cm2 for the Nd:YAG laser line mirror, which are to be compared with the 0.7 J/cm2 maximum energy density of the beam. While the broadband mirror would likely be damaged by the laser, the more specialized laser line mirror is appropriate for use with this system.

Pulsed Nanosecond Laser Example: Scaling for Different Wavelengths
Suppose that a pulsed laser system emits 10 ns pulses at 2.5 Hz, each with 100 mJ of energy at 1064 nm in a 16 mm diameter beam (1/e2) that must be attenuated with a neutral density filter. For a Gaussian output, these specifications result in a maximum energy density of 0.1 J/cm2. The damage threshold of an NDUV10A Ø25 mm, OD 1.0, reflective neutral density filter is 0.05 J/cm2 for 10 ns pulses at 355 nm, while the damage threshold of the similar NE10A absorptive filter is 10 J/cm2 for 10 ns pulses at 532 nm. As described on the previous tab, the LIDT value of an optic scales with the square root of the wavelength in the nanosecond pulse regime:

Pulse Wavelength Scaling

This scaling gives adjusted LIDT values of 0.08 J/cm2 for the reflective filter and 14 J/cm2 for the absorptive filter. In this case, the absorptive filter is the best choice in order to avoid optical damage.

Pulsed Microsecond Laser Example
Consider a laser system that produces 1 µs pulses, each containing 150 µJ of energy at a repetition rate of 50 kHz, resulting in a relatively high duty cycle of 5%. This system falls somewhere between the regimes of CW and pulsed laser induced damage, and could potentially damage an optic by mechanisms associated with either regime. As a result, both CW and pulsed LIDT values must be compared to the properties of the laser system to ensure safe operation.

If this relatively long-pulse laser emits a Gaussian 12.7 mm diameter beam (1/e2) at 980 nm, then the resulting output has a linear power density of 5.9 W/cm and an energy density of 1.2 x 10-4 J/cm2 per pulse. This can be compared to the LIDT values for a WPQ10E-980 polymer zero-order quarter-wave plate, which are 5 W/cm for CW radiation at 810 nm and 5 J/cm2 for a 10 ns pulse at 810 nm. As before, the CW LIDT of the optic scales linearly with the laser wavelength, resulting in an adjusted CW value of 6 W/cm at 980 nm. On the other hand, the pulsed LIDT scales with the square root of the laser wavelength and the square root of the pulse duration, resulting in an adjusted value of 55 J/cm2 for a 1 µs pulse at 980 nm. The pulsed LIDT of the optic is significantly greater than the energy density of the laser pulse, so individual pulses will not damage the wave plate. However, the large average linear power density of the laser system may cause thermal damage to the optic, much like a high-power CW beam.

Hard-Coated Bandpass Filter Structure

Bandpass Filter Layers
Click to Enlarge

The number of layers shown in this schematic is not indicative of the number of layers in an actual hard-coated bandpass filter. The drawing is also not to scale.

A bandpass filter is created by depositing layers of material on the surface of the substrate. For our hard-coated bandpass filters, the coating is comprised of dielectric stacks alternating with dielectric spacer layers. Each dielectric stack is composed of a large number of alternating layers of low-index and high-index material. The thickness of each layer in the dielectric stack is λ/4, where λ is the central wavelength of the bandpass filter (i.e. the wavelength with the highest transmittance through the filter). The spacer layers are placed in between the stacks and have a thickness of (nλ)/2, where n is an integer. A Fabry-Perot cavity is formed by each spacer layer sandwiched between dielectric stacks. The filter is mounted in an engraved metal ring for protection and ease of handling.

Filter Operation Overview

The constructive interference conditions of a Fabry-Perot cavity allow light at the central wavelength, and a small band of wavelengths to either side, to be transmitted efficiently, while destructive interference prevents the light outside the passband from being transmitted. However, the band of blocked wavelengths on either side of the central wavelength is small. To increase the blocking range of the filter, materials with broad blocking ranges are used as the substrate or to coat the spacer layers. Although these materials effectively block out-of-band transmission of incident radiation, they also decrease the transmission through the filter in the passband.

Filter Orientation

An engraved arrow on the edge of the filter is used to indicate the recommended direction for the transmission of light through the filter. Orienting the coated side toward the source will reduce unwanted scattering and minimize reflections sent back toward the source. Using the filter in the opposite orientation will not, however, significantly affect the performance of the filter. The plot to the bottom left was made by illuminating the filter with a low intensity broadband light and measuring the transmission as a function of wavelength. The plot shows that the direction of transmission through the filter has very little effect on the intensity and the spectrum of the light transmitted through the filter. The minimal variation between the forward and backward traces is most likely due to a small shift in the incident angle of the light on the filter introduced when the filter was removed, flipped over, and replaced in the jig.

The filter is intended to be used with collimated light normally incident on the surface of the filter. For uncollimated light or light striking the surface at an angle not normally incident to the surface, the central wavelength (wavelength corresponding to peak transmission) will shift toward lower wavelengths and the shape of the transmission region (passband) will change. Varying the angle of incidence (AOI) by a small amount can be used to effectively tune the passband over a narrow range. Large changes in the incident angle will cause larger shifts in the central wavelength but will also significantly distort the shape of the passband and, more importantly, cause a significant decrease in the transmittance of the passband, as seen in the plot to the bottom right.

Filter Temperature

The central wavelength of the filter can be tuned slightly (~1 nm over the operating range of the filter) by changing the temperature of the filter. This is primarily due to the slight thermal expansion or contraction of the layers.

I'm wondering if you could provide information on whether the CWL can be angle tuned for the FBH series (as is typical for dielectric coated bandpass filters). I assume there's no absorptive element in these? In my case I would be interested in whether the FBH1300-12 can be angle tuned to pass 1250nm and rough performance.

Thank you for reaching out to us David. I can't speak for certain if the FBH1300-12 will have 50nm shift at the max tilt angle, but I can confirm that these components are capable of angle tuning 10's of nm as a function of tilt angle with the dependence being stronger with larger center design-wavelength. I have reached out to you directly with some test data.

For a hard-coated filter like FBH405-10, what is the typical filtering performance at a non-zero incidence angle? Any comments about the expected magnitude of shift of CWL or FWHM as a function of small incident angle errors would be helpful. Is the behavior similar to a simple few-layer interference filter? Thank you.

Thank you for contacting Thorlabs. Small AOI errors in alignment should not have a large effect on either CWL or FWHM. I have contacted you directly via email to discuss this further.

Dear Madam or Sir, My name is Diogo and I'm an optical systems engineer, but also an amateur astronomer. For my hobby, I'm very interested in your filter FBH850-40 for filtering light affected by atmospheric absorption lines (eg. H2O, O2). Could you please tell me the manufacturing tolerance for the center wavelength and FWHM? Also, do you have available out of tolerance filters that you might sell for a reduced price? Thank you in advance, Diogo Rio Fernandes
YLohia  (posted 2020-08-18 09:18:16.0)
Hello Diogo, thank you for contacting Thorlabs. The typical tolerance on the FWHM is around ±1 nm. Unfortunately, we do not have a tolerance on the CWL, but we do require that the part meet %T at the nominal CWL. So given the tolerance on the FWHM, that ensures that the 850 nm filter will pass 850 nm at the 90% transmission we specify, even if the passband is shifted slightly. In a sense, this acts like a tolerance, since given the shape of the passband, the nominal CWL cannot be missed by much.

Hello, thank you for your feedback. We will post this on our internal product engineering forum for further consideration.

I'm looking for a filter that can be used on an F/4 telescope and have good narrowband transmission at 1010nm. The 1030-10 filter might be suitable given the F/4 characteristic will move the CWL but I can also mount the filter at a small tilt if this is needed to maximise the throughput at 1010nm. I need to know some specifics abt the filter, ie refractive index etc to calculate this, can someone plz get in touch. Best regards.

Hello, thank you for contacting Thorlabs. The substrate for this filter is UV Fused Silica, which has an index of refraction of 1.4503 at 1010nm.

Is it possible to produce bandpass filter for a deeper UV region with a reasonable transmission (70-100%) ? We are interested in the band-pass for 300nm to clean-up the emission of 300nm LED (M300L4). Thank you.

What's the expected lifetime of this type of filters?
nbayconich  (posted 2018-02-23 10:16:23.0)
Thank you for contacting Thorlabs. We do not have an expected lifetime for these hard coated dielectric filters but we do offer a two year warranty for them. The performance should not deteriorate if used properly in standard laboratory conditions and not in a field environment where the optics could be exposed to harsh elements such as moisture, dramatic temperature change etc. I will reach out to you directly to discuss your application.

I am looking for a filter which can block 795 nm and pass 780 nm wavelength. Is FBH780-10 will be useful for these purpose? Do these filters have any polarization dependency? If I send a s-polarized 780 nm beam and circular polarized 795 nm beam then is there any leakage of 795 nm beam?
tfrisch  (posted 2017-12-19 04:31:20.0)
Hello, thank you for contacting Thorlabs. FBH780-10 is designed for normal incidence at which there is nothing to discern S from P polarization. Even at small angles, I would not expect a large dependence on polarization state. As for the wavelength performance, blocking regions for FBH780-10 are 200-752nm and 808-1200nm. Though nominally, 795nm is not within this blocking region many production lots still have quite high extinction of the wavelength (see the raw data of the OD plot). You may be able to angle tune the filter increase the extinction. Please reach out to me at TechSupport@Thorlabs.com to discuss this in greater detail.

I would love to see one of the premium bandpass filters available for use at 671. The FWHM isn't that important. Thanks, David

Hello, thank you for contacting Thorlabs. I have reached out to you directly, but I also want to point out that FL670-10 is a soft-coat filter with the nearest CWL.

I am looking for a bandpass filter with similar (impressive) specs as your premium line of BP filters but lower down in the UV. Since the substrate you use is fused silica, can you manufacture a BP filter with center wavelength at 385nm with 40nm BW? If this has to be custom made, how much would it cost?
elkeneu  (posted 2015-04-15 16:21:24.89)
Suggestion for a bandpass filter: A new often used emitter system is the so called nitrogen vacancy center in diamond. It is now used in lots of sensing, labeling and imaging applications. It is very hard to find a bandpass filter to transmit its broadband fluorescence between 640 and 770 nm. such a filter would be highly useful in your premium filters line.
besembeson  (posted 2015-04-21 10:48:46.0)
Response from Bweh at Thorlabs USA: Thanks for your interesting suggestion regarding such a filter. It would certainly be a good addition to this product line. Our Optics division will consider if we can develop such an optic. It will probably not be available short-term though.
gedge  (posted 2015-02-03 14:29:48.85)
I am looking for a bandpass filter similar to this one, but with a center wavelength in the range of 767nm-770nm (we are performing atomic physics with Potassium). Is it very expensive to create a 'premium' version of one of your 770nm bandpass filters (FB770-10)? Thanks for your time, Graham Edge Graduate Researcher University of Toronto, Department of Physics
besembeson  (posted 2015-02-12 01:24:48.0)
Response from Bweh at Thorlabs USA: We can provide custom versions of these premium bandpass filters. I will followup with you by email regarding the quoting possibility.

How much damage threshold can be expected for premium bandpass filter?
tcohen  (posted 2013-10-03 12:37:00.0)
Response from Tim at Thorlabs: These will have a higher LIDT threshold over our standard immersed dielectric bandpass filters but we do not yet have an experimental data set. As it will vary with the light source and the amount in the pass/rejection band as well as the general operating beam parameters (frequency, pulse duration) we would like to discuss your beam parameters. I see that you haven’t left us any contact information, so please contact us at techsupport@thorlabs.com so we can discuss this in more detail.

Premium Visible Hard-Coated Bandpass Filter Kits

Thorlabs' Visible Bandpass Filter Kits each contain 10 mounted premium hard-coated bandpass filters that can be used to transmit a well-defined wavelength band in the visible, while rejecting other unwanted radiation. Each filter is mounted in an unthreaded Ø25.0 mm black-anodized aluminum ring that can be placed into our selection of Ø1" lens tubes and filter mounts using retaining rings. The filter kits come in a convenient plastic box for storage and transportation purposes.
