Thorlabs and RPC Photonics are proud to offer Engineered Diffusers™, which provide non-Gaussian intensity distributions in various patterns. We offer square, circular, and line distribution tophat patterns with a 90% transmission efficiency. The square and circular patterns are offered in 20° and 50° divergence angle options, while the line distribution has a 0.4° x 100° divergence. Typical diffusers do not offer this advanced light control. These Engineered Diffusers are designed for use with Ø0.5 mm or larger laser beams; smaller beams should be expanded prior to the diffuser.

Our Engineered Diffusers are available unmounted or mounted. The mounted Ø1" diffusers come in an engraved SM1-threaded (1.035"-40) mount, as shown at the top of the webpage. The mount provides quick identification and helps protect the diffusers from fingerprints and other contamination. SM1 threading is particularly useful when building Ø1" lens tube and 30 mm cage systems. These mounted diffusers are available individually or as a set of all five at a discounted price.

Please see the Technology tab above for more information on our Engineered Diffusers.

Engineered Diffuser Technology
Thorlabs and RPC Photonics' Engineered Diffusers™ provide advanced beam shaping that leads to significant performance enhancements for applications as diverse as lithographic systems, outdoor lighting, displays, backlighting, display brightness enhancement, and projection screens.

Homogeneous diffusers made of, for example, ground glass, opal glass, or holographic elements, consist of repeating, uniform surface patterns across the entire clear aperture that provide only limited control over the shape and intensity profile of the illuminated area, causing the incident light to be used inefficiently. In addition, holographic diffusers are usually limited to monochromatic applications using coherent light. On the other hand, Engineered Diffusers consist of differing, individually manipulated microlens units that provide broadband compatibility and excellent control over the light distribution and beam profile.

Each microlens unit that forms the diffuser is individually specified with respect to its surface profile and location in the array. At the same time, to ensure that the diffuser is stable against variations in the input beam's intensity profile and usable in the visible and IR, the distribution of microlenses is randomized according to probability distribution functions chosen to implement the desired beam shaping functions. The microlens distribution also removes zero-order bright spots and diffraction artifacts from the output. In this manner, Engineered Diffusers retain the best properties of both random and deterministic diffusers.

Diagram of Mastering Process

Fabrication
The master microlens array is produced by a laser writing system developed by RPC Photonics. This system exposes a thick layer of photoresist point-by-point in a raster scan mode, as shown to the left. By modulating the intensity of the laser beam as it is scanned, the degree to which the photoresist is exposed can be varied. A deeply textured, engineered surface is the result, as shown above in the two SEM images of the surface topography.

Comparison to Other Diffuser Technologies
Other common diffuser types include prismatic glass integrating bars, ground glass, opal glass, holographic diffusers, and diffractive diffusers. Prismatic glass integrating bars, though sometimes used in high-end systems, are expensive and occupy a great deal of precious space. Ground and opal glass scatter light equally in all directions but with a low degree of control. In addition, efficiency is generally poor with these simple diffusers. Holographic diffusers are an improvement on these technologies and enable limited production of light distribution patterns, but only offer Gaussian-like intensity profiles and circular or elliptical patterns. In terms of general beam shaping capability, diffractive elements can shape an input beam arbitrarily. However, they are confined to narrow diffusion angles, highly sensitive to wavelength, and cannot eliminate zero-order bright spots collinear with the incident beam.

In contrast, Engineered Diffusers provide high transmission efficiencies and the ability to control the divergence angle, spatial distribution, and intensity profile of the diffused light.

Introduction
Engineered Diffusers are designed to create non-Gaussian intensity distributions in circular or square beam profiles that diverge from the plane of incidence. Below, to the left of the page, are the theoretical approximations of the intensity through the center of the diverging beam profile when illuminating the engineered diffusers with a 633 nm collimated beam. To the right are data compiled from independent tests with laser wavelengths of 488 nm, 637 nm, 785 nm, and 1064 nm to demonstrate the change in output profile with wavelength. At the bottom of this tab is a description of the laboratory setup and procedure used to collect these data and the results.

Procedure
Four wavelenghts of light were chosen for study: 488 nm, 637 nm, 785 nm, and 1064 nm. These were prepared using the equipment to the right (a full list of all parts used can be found under the photo of the Experimental Set Up).  The optical path was approximately 35 cm above the surface of the breadboard; it began when fiber-coupled light sources were collimated with triplet collimators, using a design wavelength as close to the source wavelength as possible. In free space, the beams were incident upon one of the Engineered Diffusers. The exiting divergent profile was isolated and focused by an with an LA1304 plano-convex lens attached to an SM05L20 lens tube. The signal was sampled every 0.5° by a SM05PD1A photodiode. This assembly was mounted on the end of an XT34-500 rail. The opposite end of the rail was mounted to a NR360S rotation stage centered with the engineered diffuser under test in order to sweep the detector and lens assembly through the center of the profile, as illustrated below, and plot normalized intensity versus output angle. The distance between the diffuser and the detector was approximately 43 cm. The output angle was defined with respect to the original optical axis when the diffuser was not within the path. In order to control for ambient light, a 1 kHz sine wave was used to modulate the drive current applied to the laser diode and the signal was acquired with a lock-in amplifier. A LabVIEW program was written to control the setup and acquire the data.

Experimental Limitations
Only one of each Item # was testeda. Stability may have been compromised by the experiment being performed on a PBG11113b breadboard without any isolation. Only the middle of each diffuse shape was measured, so variances in other areas of the shape are possible, including the corners of the square profiles. 

Results
It was found that there was little variance in diffuse beam profile with respect to wavelength across the middle of each beam profile. Above, to the left of the page, are the theoretical estimations of intensity accross the width of the resulting beam profile. Above are data compiled from independant tests with various laser wavelengths to verify the theoretical models.

Hi! I have twe questions about line pattern diffuser. 1. How can I align the diffused line pattern with my sample? 2. Is it effective to use two diffusers for more wider and uniform pattern?
nbayconich  (posted 2019-09-27 03:06:02.0)
Thank you for contacting Thorlabs. The alignment procedure can be very application dependent, I would recommend possibly using a rotation mount to hold this diffuser so you can control the angle of the line pattern. In terms of using a second diffuser this wouldn't necessarily improve your pattern uniformity. If needed you can collimate the pattern by placing a lens after the diffuser. I will reach out to you directly to discuss your application.

Hi! We plan to use these diffusers with a collimated (2W 830nm) laser diode. Do you know their damage threshold? We can adjust a bit the beam diameter, but we are not able to change it a lot. The documentation and the feedbacks talk about "low-power applications", without specified limit. Could you precise a bit more? (in terms of power density for example) Thanks a lot.
YLohia  (posted 2019-09-25 10:01:36.0)
Hello, our engineered diffusers have not been formally tested for laser damage. However, distortion from heat occurs at ~ 99°C. These are not intended to be used with high power lasers. If you're looking to convert a Gaussian intensity profile to a flat-top profile, our apodizing filters such as the NDY10B could be something to look into. Unfortunately, we have not yet performed intensive damage threshold testing on these optics. That being said, these were designed for low-power applications so it would be best if you are able to use the maximum possible beam diameter for a lower power density.

I have a inquiry for these products (engineered diffusers). If polarized laser pass through this diffuser, the polarization state preserves? Or become unpolarzed light? I look forward to your answer. Thank you. Best regards
nbayconich  (posted 2019-09-06 09:06:29.0)
Thank you for contacting Thorlabs. These diffusers should not rotate your polarization state and there will be no polarization scrambling caused from these engineered diffusers. There may be increased Fresnel reflection loss depending on the input polarization and orientation. A Techsupport representative will reach out to you directly to discuss your application.

I've noticed inhomogenetity in the way ED1-S20 affects my polarization. There is one spot on the diffuser which rotates the polarization from horizontal to vertical (the diffused square is oriented horizontally too, not diamond). Is this inhomogenetity expected or is it a defect? (if I buy another one, am I likely to have the same problem?)

Good Evening, I have a question about these diffuser : if I use a collimated laser light (CW @1053nm), the output light will diverge with a known angle (20° or 50°): will we able to collimate the output beam with a lens?
nbayconich  (posted 2019-02-05 08:30:45.0)
Thank you for contacting Thorlabs. After your collimated source passes through the engineered diffuser, your source can no longer be considered a single point source therefore not possible to perfectly collimate. A lens can be used after the diffuser to help reduce the amount divergence created by the diffuser however the beam size will still diverge as a function of distance and the intensity distribution will not maintain a perfectly flat top profile. A high NA lens like a condenser asphere can be used for example.

Hi, I am looking for homogenizer for pulsed 355nm beam having around 150mJ per pulse in 6.5 mm diameter. Is ED1-S20 suitable for my purpose? Or can you recommend another one? Thank you!
YLohia  (posted 2019-01-23 11:27:04.0)
Hello, our engineered diffusers have not been formally tested for laser damage. However, distortion from heat occurs at ~ 99°C. The specifics of the damage would depend on the peak power, pulse width, and rep rate of your source. These are not intended to be used with high power lasers. If you're looking to convert a Gaussian intensity profile to a flat-top profile, our apodizing filters such as the NDY10B could be something to look into.

What is the fringe visibility? Do you have a zoomed in image of the pattern? Will the diffuser work with a non-collimated beam?
nbayconich  (posted 2018-10-12 09:50:22.0)
Thank you for contacting Thorlabs. The fringe or speckle pattern will depend on the coherence length of the source being used, If the laser has good spatial coherence the speckle will be noticeable and the contrast will be high. The input beam does not need to be Gaussian or circular shape to produce a square output and a slightly diverging source can be used as well however to achieve the best results the source must be collimated to avoid sharp features appearing from the diffuser's output. I will reach out to you directly to discuss your application and show you a few examples of the square pattern engineered diffusers output image.

Hi, I use ED1-C20-MD with 515nm picosecond with 10W/cm2. Input laser is collimated but due to long travel range speckles are serious. After passing the diffuser, many small grit-shaped circles appear. How to get better putput? Thank you Yayao
nbayconich  (posted 2018-10-12 10:32:29.0)
Thank you for contacting Thorlabs. If the laser source has good spatial coherence then the speckle will be noticeable and the contrast will be high. Users of diffusers must work out a method for speckle mitigation which would include aperture averaging or some other type of averaging such as motion over time with finite integration. One such example is to rotate the diffuser in use. Alternatively lower coherence sources such as LED or white light will show no speckle.

Hello, could you send me the transmission curve for this diffuser at 380-600 nm range? Also, I will use a 400KHz femto laser with thousands W/cm2, will this diffuser be suitable? Thanks.
YLohia  (posted 2018-06-14 09:32:45.0)
Hello, I have sent you the curve via email. We do not recommend this diffuser for such high power applications.
user  (posted 2018-05-18 09:40:14.25)
It would be helpful to know how the diffuser impacts the polarization of light. Typically ground glass diffusers scatter light with random polarization. These engineered diffusers probably don't change the polarization, but it would be useful for the customer to know the polarization performance.
YLohia  (posted 2018-05-23 11:22:12.0)
Although your light does stay polarized, the actual state of polarization will change based on the input polarization of the light, as well as the location of the beam on the optic. For example, the magnitude of this change will be less if the polarization state is in line with the corners of the square diffuser. If your original polarization state is parallel to either side of the square, however, you will see a large amount of circularization.

Can you please provide the transmission curve for this diffuser from 350-650 nm. I would imagine the plastic will start to absorb somewhere in the UV, but it would be helpful to know where exactly that takes place.
YLohia  (posted 2018-03-30 12:15:55.0)
Response from Yashasvi at Thorlabs USA: Hello, thank you for contacting Thorlabs. You are correct, these will start absorbing light in the UV region, starting roughly ~320-350nm. Please note that we don't recommend using these for <400nm since there is some variation in the transmission below that wavelength from lot to lot. I will reach out to you directly with a typical transmission plot.

Hello, My name is Hoon Yu and I'm very interested in your engineered diffuser. I have two questions. 1.Is there any polarization dependence in your diffuser? For example, transmission as polarization or beam shaping efficiency as polarization? 2. After the diffuser, is the laser polarization changed or maintained? Thank you for your consideration. Bests, Hoon.
nbayconich  (posted 2017-10-16 12:21:10.0)
Thank you for contacting Thorlabs. The transmission of this material has little polarization dependence. There may be increased Fresnel reflection loss depending on the input polarization and orientation. For optimum performance align P polarization with the large diffusion axis in this case. There will be no polarization scrambling caused from these engineered diffusers.

guy.whitworth  (posted 2017-05-25 15:24:08.873)
Does the output beam maintain a degree of coherence? Would it still diffract well if incident on a grating?
nbayconich  (posted 2017-06-08 09:46:08.0)
Thank you for contacting Thorlabs. Once your coherent source passes through these diffusers it will no longer be coherent. Diffusers scatter light at different angles essentially eliminating and coherence of your source. This will not allow distinct modes to be diffracted from a grating. A techsupport representative will reach out to you directly with more information.

The specs simply state that the transmission is 90%. Similarly the chromatic dependence is normalized per trace. Can you please send me more detailed information about the transmission as a function of wavelength? I would like to know, for example, when changing the source wavelength from 500 nm to 700 nm, how much light will be lost or gained? Similarly you could post the integrated power. The easiest way to measure this is to use an integrating sphere to capture the light after the diffuser, connect a calibrated power meter to the output port of the integrating sphere, and use a calibrated source to measure this information. I hope you could provide this information, it will be very helpful. Thanks very much and I look forward to hearing back from you, Ron

besembeson  (posted 2015-10-09 02:59:28.0)
Response from Bweh at Thorlabs USA: That is the most power density that we have tested without causing damage. It could withstand higher powers but for 2-4 times and at 450nm, it will be better to consider the high power version. I will contact you regarding quoting this please.

besembeson  (posted 2015-02-26 04:39:54.0)
Response from Bweh at Thorlabs USA: The engineered diffusers will not work the same. Unlike the pi-shaper, the output from the engineered diffusers will not be collimated but will have a fixed divergence. Regarding the interference fringes, we have not tested this. However, what you would likely observe is a degraded fringe visibility.

For the ED1-C50, as a comparison, it will be +/-26.1deg and +/-24.5deg at 400nm and 950 nm respectively.

Does this diffuser works only with collimated beam? What should I expect if i put this soon after a fiber whit a given angle of divergence?
besembeson  (posted 2014-10-30 04:07:38.0)
Response from Bweh at Thorlabs USA: The angular spread that is specified for the engineered diffusers assumes a collimated input which is what is recommended. You can use a divergent source but the output divergence will be increased by a factor dependent on the divergence of the source. As an example, for a 0.22 NA fiber (~25 deg divergence), with the ED1-S20, the output divergence will increase by a factor of about 2.25 the engineered divergence angle specification.

Response from Bweh E at Thorlabs: Thanks for contacting Thorlabs. If all three are focused on different points on the diffuser, each point sources will create its own diffused patterns.

Response from Javier at Thorlabs to dspan: Thank you for your inquiry. If you input polarized light into the Engineered Diffusers, the output will still be polarized. Although your light does stay polarized, the actual state of polarization will change based on the input polarization of the light, as well as the location of the beam on the optic. Let’s take the square diffusers as an example. In general, you will get less of an effect if the polarization state is in line with the corners of the square. If your original polarization state is parallel to either side of the square, however, you will see a large amount of circularization (more circular than linear). I hope this helps.

Unmounted Engineered Diffusers

  • Ø1" Engineered Diffusers
  • Circle, Square, or Line Pattern Diffusers

Unmounted optics are ideal for applications that are tight on space or that need added mounting flexibility. Our Ø1" unmounted Engineered Diffusers are commonly used in SM1-threaded (1.035"-40) lens tubes. The optic should be oriented so that incident light hits the engineered surface.

Mounted Engineered Diffusers

  • Ø1" Engineered Diffusers in SM1 Threaded Mounts
  • Circle, Square, or Line Pattern Diffusers

Our mounted Engineered Diffusers are the same as their unmounted counterparts, but are set in an SM1-compatible engraved mount. Mounted optics have the advantage that they are easy to identify and the optics are recessed in the mount so that they are better protected from contamination than unmounted optics. The optic should be oriented so that incident light hits the engineered surface first; when the optic is placed in its mount, this side will be closest to the retaining ring.
