Light-emitting diodes (LEDs) are compact, energy-efficient light sources that can emit light over a wide range of wavelengths. Thorlabs offers unmounted LEDs for center wavelengths from 250 nm to 4.5 µm. These unmounted LEDs are packaged in a variety of TO-can style housings, including T-1 3/4, TO-18, TO-39, and TO-18R. Our UV LEDs are available with either an integrated window or ball lens, while all other LEDs are offered epoxy encased or with a glass lens, flat window, or a parabolic reflector. Post-mountable and SM-threaded passive mounts, as well as a socket for LEDs, are sold separately below.
Use the Quick Links table to the right to view LEDs within a specific wavelength range. General information about each LED is provided in the tables to compare specifications. Complete specifications and a spectrum plot are provided in the spec sheets, which can be accessed by clicking on the red docs icon (
) next to the Item # below.
Due to unmounted LEDs typically having significant divergence angles, the output light frequently needs to be focused through a lens for use within an experimental setup. Aspheric condenser lenses (available uncoated for 380 - 2100 nm or with an AR coating for 350 - 700 nm or 650 - 1050 nm) are ideal for collimating the light from our unmounted LEDs with a center wavelength from 405 nm to 1600 nm. Unmounted LEDs with center wavelengths from 1650 nm to 4500 nm feature parabolic reflectors that reduce the output divergence angle. The Characterization tab describes sample methods and equipment for characterizing the light output from the majority of LEDs offered on this page. To discuss other options, please contact Tech Support.
| If you do not see an LED with the wavelength/color, optical power, or viewing angle desired, please contact Tech Support, and we will work to obtain one for you and consider adding it to our permanent offerings. |
Light-Emitting Diode (LED) Characterization Methods
Thorlabs offers the items and equipment necessary to characterize the light emission properties of the majority of LEDs sold on this page. The different specifications which may be determined using the methods and equipment below are:
- Spectral Distribution
- Full Width at Half Maximum (FWHM)
- Radial Intensity Distribution
- Half Viewing Angle
- Forward Radiated Optical Power
- Total Optical Power
Measurement Technique for Spectral Distribution and FWHM
A CCS200(/M) Fiber-Coupled Compact Spectrometer connected to a computer can be used to measure the spectral response of LEDs in the UV*/visible wavelength range (200 - 1000 nm; for LEDs emitting in NIR, use the OSA202C). The LED may be powered by an LD1255R Laser Diode Driver operating in constant current mode. The light from the LED is focused by an LB1761 Bi-Convex Lens, f = 25.4 mm, into a Ø50 µm core multimode fiber patch cable with SMA905 connectors attached to the spectrometer.

*Please note that the CCS200 spectrometer cannot be amplitude calibrated below 380 nm. When performing broadband power measurements, a large difference in the relative response of the system from the UV to the visible inhibits reliable power readings in the UV.
Measurement Technique for Radial Intensity Distribution and the Half Viewing Angle
To make a measurement of the intensity pattern as a function of angle, the LED can be rotated on an axis perpendicular to the axis along which the emitted light intensity is the greatest. Goniometric rotation of the LED is achieved by mounting the LED on a post attached to a Motorized Rotation Stage so that the rotation axis goes through the light emitting surface of the LED. The stage is controlled by a brushed DC servo motor, such as our KDC101, while the LED is powered by an LD1255R Laser Diode Driver. The radiated light is detected using either a Si or Ge Photodetector, DET36A2 or DET30B2 respectively, located approximately 12 inches from the LED. The S05LEDM LED Mount is recessed within the SM05M10 Lens Tube such that the front of the LED is centered above the center of the rotation stage. To keep stray or scattered light from hitting the detector, SM1 Lens Tubes are attached to the detector that extends to just short of the LED. Two SM1D12C Iris Apertures are placed along the path from the LED to the detector. The iris closer to the LED has an aperture diameter of 10 mm while the aperture nearest the detector has a diameter of 3 mm.
As the LED rotates, the output of the photodiode detector, which is proportional to the light intensity, is recorded for each angular position using a data acquisition card. The LED is rotated from +90° to -90°, where 0° approximately corresponds to when the axis of maximum intensity is parallel to the detector axis. The half viewing angle specification is determined by the angle that corresponds to a 50% drop from the maximum detector output.

Measurement Technique for Determining the Total Optical Power
The total optical output power of an LED can be measured using an integrating sphere. The radiated light is detected using either a Silicon (for UV or visible wavelength LEDs) or InGaAs (for NIR LEDs) Photodiode and Integrating Sphere, such as the IS200 with SM05PD2A or IS210C, respectively. The sphere may be calibrated with a laser source such as the Thorlabs CPS635R Laser Diode Module. The output of the photodiode can be amplified and measured using our PDA200C Benchtop Photodiode Amplifier.

Do-It-Yourself USB LED
A Universal Serial Bus (USB) port can be used to quickly power many of the Light Emitting Diodes (LEDs) on this page for temporary use. USB ports are used in a variety of applications like charging batteries and transferring data; they are commonly found on computers, but they are increasingly found on other electronic devices, and even incorporated into wall outlets. This tab presents a step-by-step tutorial to take advantage of this port in order to power an LED. Take note of the spec sheet for the LED being used; if its Typical Forward Voltage is listed higher than 5 V, the LED will not be able to be powered by a USB port (this is explained using Equation 2 below). Spec sheets can be downloaded by clicking on the () icon next to desired item.
Example Application
It is possible to create a continuous lighting setup using an LED525L from the Thorlabs catalog, powered by a USB port. A
100 Ohm resistor should be used for this system. For an explanation on how this was determined, see Equations 3 and 4 below.
Warning
This tutorial contains instructions that require the creation of an electrical circuit, including the use of a soldering iron. Please be advised that the user is fully responsible for following proper practices with regards to creating an electric circuit when following this procedure. For other LED power solutions, visit our selection of current controllers for LEDs
Procedure (Click Images for Details)
If the chosen USB wire is repurposed with two ends, unplug both ends and cut off the non-Type A Male end, leaving as much slack on the Type A Male end as possible using Wire Cutters.
If heat shrink tubing will be utilized, place a length of two inches down the wire for later.
Strip the outer plastic about two inches from the end, being careful not to cut too far into the wire.
The wire will contain shielding and four smaller wires: Red (+5 V), Black (Ground, 0 V), White and Green. The latter two wires are used for data transfer.
Cut away an inch of the red wire, any exposed shielding, and the white and green wires down to the main wire's remaining outer plastic while stripping the Red and Black wires to give enough room for a solder joint.
Solder one end of the resistor (resistors are bidirectional, either end will do) to the red wire. The end of the resistor's lead and the black wire should be roughly the same length.
Find the positive pin on the LED, the anode, which can be found on the LED's Spec Sheet, and solder it to the resistor.
Solder the remaining, negative end of the LED, the cathode, to the black wire.
Once the solder has cooled, wrap each connection separately in a layer of electrical tape. Warning: Improper insolation of exposed metal can lead to shorting of the circuit, electrical failure, or fire.
Either cover the wrapped wires in electrical tape, or, if heat shrink tubing was placed down the wire, slide it up over the connections, and slowly heat with a heat gun or hair dryer until it snugly fits over the connections.Parts List
Components:
- An Unmounted LED
- A Type-A Male Connector USB Wire with Pigtails
- A Resistor (See Choosing a Resistor)
- (Optional) 5 VDC External Battery Pack (CPS1)
- (Optional) Repurposed USB with Type-A Male Connector (USB-C-36)
Tools:
- Wire Strippers
- Electrical Tape
- Soldering Iron
- Solder
- Helping Hand
- (Optional) Heat Shrink Tubing
- (Optional) Heat Gun or Hair Dryer
Choosing a Resistor
USB ports can produce up to 500 mA or higher in some cases, which is too much current for most LEDs. For this reason, an LED connected directly to a USB cable will burn out within a matter of hours. Placing a resistor before the LED in the circuit will reduce the current coming from the USB port, and allow the LED to operate.
To find the best resistor for the job, start with Ohm's Law, which gives the voltage across a wire,
V=IR (Equation 1),
where V is Voltage, I is Current, and R is Resistance.
V here will be the difference between our voltage output from our source (Vs ), and the forward voltage of our LED (Vf ), found on the chosen LEDs spec sheet. Vf can be thought of as a threshold the current needs to overcome to get the LED to light up. Replacing the difference into Equation 1 yields
(Vs-Vf )=IR (Equation 2).
I will match the operating current for our LED, found on the chosen LEDs spec sheet; rearranging the equation for R yields
R=(Vs-Vf )/I (Equation 3).
Choose the resistor that is the closest match rounding up.
Looking at the specification sheet for the LED525:, the Maximum DC Forward Current is 30 mA and the Typical Forward Voltage is 3.0 Va. To keep the LED running at a current lower than the maximum, 20 mA will be chosen for the current. Knowing that a USB port has a 5 V potential, Equation 3 results in the following:
R=(Vs-Vf )/I = (5 V-3 V)/.02 A = 100 Ohm (Equation 4).
A 100 Ohm resistor is a standard size, so no rounding up is needed.
Portable Battery Pack
This system can be mobile with the addition of a 5 VDC External Battery Pack (CPS1), which is sold by Thorlabs. This device acts just like any other USB Type A female port. Alternatively, a battery holder can be hard wired on as long as the batteries supply a higher voltage than the LED's forward voltage Vf . In the case of adding a battery holder, Equation 3 is still applied, except changing the Vs to the batteries voltage. It may also be beneficial to add a switch to your circuit, so that way the LED can be switched on and off without needing to remove it from the power supply.
Powering Multiple LEDs
If more than one LED is needed, they can be combined in either series or parallel. If placed in series, LEDs' Vf will stack, requiring a larger Vs . A parallel configuration is more advantageous for LEDs; in this configuration, more current is needed from the power source, but the Vf can be satisfied on an individual basis by Vs . While in parallel, it is also very important that each LED has its own resistor, calculated as if each LED was independently connected to the battery, or the system will risk a total burn out if one LED fails, as each remaining LED would attempt to bear the current of the dead LED.

We would need this device with the colors green, red, and IR (preferably with light >1050nm, this would be an 1200nm-IR-LED). Would this be possible to generate such a product?

(posted 2019-12-11 14:17:16.027) Why does 1450nm infrared LED, after lighting for a period of time (about 2 hours), reduce the luminous intensity by 30%? Is it related to the way of heat dissipation? If so, how to cool it?
Which is the main cooling surface of this led? dpossin
(posted 2019-12-12 10:18:20.0) Dear customer,
Thank you for your feedback. As the LED1450L has a power consumption of 50mW but emits an optical power of 5mW, the heat dissipation is 45mW. Therefore it is needed to introduce thermal management. I am reaching out to you in order to provide further information. Ludovic Angot
(posted 2019-08-05 03:51:22.137) Please review the spec sheet of your LEDRGBE RGB led, as of the date of posting it is incorrect: a 2 pins LED is shown in section 2.5 and with the wrong anode and cathode configuration. Also do you confirm that the max DC forward current (stated at 50mA) is valid for each individual RGB channels? MKiess
(posted 2019-08-07 08:55:09.0) This is a response from Michael at Thorlabs. Thank you very much for the feedback. You're absolutely right that this representation is incorrect. We will correct it immediately. The DC forward current of 50mA is valid for each individual RGB channels. Thank you very much for this information. Sanket Shah

(posted 2019-08-29 06:58:13.0) Hello Sanket,
Thank you for your feedback! We are currently updating the manual in question to achive a better usability for our customers. We recommend using Quasi Continues Wave mode with a duty cycle 50% or 25% to obtain maximum average optical power and short Pulse modes to obtain maximum peak power. Hard CW mode is not recommended. The maximum voltage for qCW mode @ 2A is 0.8V. I hope that helps. user

(posted 2018-01-25 09:32:05.387) 1. Optical Output Power is the total power before the lens or the power after the lens?
2. Since it’s a tiny lens, the light collimating efficiency can't be very good,how much would that collimating efficiency be about?
3. Do you have the distribution figure before collimating for LED450L,the LED chip? So I can decide how the distribution is changing,or is it worth to sacrifice the LED power?
4. What's the best you can do to achive a much better collimated LED with such conpact package? Or should I say is it possible?
THANKS. nbayconich
(posted 2018-02-16 09:42:44.0) Thank you for contacting Thorlabs. The optical power is specified after the lens or window in these types of LED packages. We do not specify a collimating efficiency for use with an additional lens, the ability to collimate an LED will depend on the divergence and chip size of the LED however it is not possible to perfectly collimate an LED source in the same way a laser diode can be.
Please see our spec sheet located below for more information about the intensity distribution vs. angle below.
https://www.thorlabschina.cn/_sd.cfm?fileName=QTN015134-S01.pdf&partNumber=LED450L
If you use an AR coated lens to collimate this LED your loss in power should be reduced to a minimum. I recommend using one of the condenser aspheric lenses to collimate these LED's, and if the intensity distribution is not suitable for your application a diffused surface aspheric lens may be a better option.

I am currently using LEDs in pulsed operation with a driver circuit closed to the figure 1 of this link: http://elib.dlr.de/64324/1/mst075402_ledpiv_willert_2010.pdf
It works very well with the LED528EHP, with large increase of average optical output power. However when using the LED1450E (with adapted Vs), the output power is not increased (compared to continuous operation). Do you recommend a specific schematic for the pulse operation of InGaAs LEDs?

(posted 2014-02-17 18:13:15.003) Hi, is there any mount, that is compatible with the S1LEDM, available for a 3mm T1 packaged LED? Thanks cdaly
(posted 2014-02-25 04:02:07.0) Response from Chris at Thorlabs: Thank you for your feedback. At the moment we do not have an adapter which will allow a T1 package LED to be mounted in the S1LEDM or any of our other LED mounts. I apologize for any inconvenience this may cause. We will look into adding such an adapter in the future. mc.guacheta177
(posted 2013-10-28 08:11:58.907) Hi, I am a researcher at the Los Andes University and I am working with the infrared spectrum. I would like to know if there is any adaptation or conditioning circuit so I can use element LED4300P. Thank you very much. jlow
(posted 2013-10-29 14:46:00.0) Response from Jeremy at Thorlabs: We do not have an operating circuit available for the LED. However, you can use a constant current source (we recommend that this be driven with a quasi-CW or pulsed signal) to drive this LED. I will contact you to provide more information on this. a.andreski

Do you know what is the emitter area of the 370E (I suppose all the unmounted LEDs here are single-emitter sources)?
Aleksandar pbui
(posted 2013-10-31 04:16:28.0) Response from Phong at Thorlabs: The emitter area of the single-emitter LED370E is 350um x 350um. kevinserg
(posted 2013-09-06 12:05:54.977) Good afternoon.
I have some questions about LED2350P.
1)There is LED2350P Package TO-18(with Reflector) drawing on 3th page LED2350P datasheet. There is "window" on top LED2350P Package on the drawing. Word "window" is red color.
But we buy 2pieces of LED2350P without any window. Why there isn`t window on top our LED2350P? Now we place an order on 1 piece of LED2350P in firm Eurolase (in Russia). Can you make LED2350P with protective window for us? Is this window option?
2) You should correct and write warning in LED2350P datasheet: "LED2350P anod is connected to the LED2350P Package!"
3) We use LED2350P in such pulse mode regime: twidth=5uS, tperiod=0.5Sec, Ipulse=1A. LED2350P is mounted on heatsink. Can I use these pulse mode parameters for LED2350P? I can`t make twidth=1uS, as recommended in LED2350P datasheet.
Best regards, Sergey. jlow
(posted 2013-09-11 15:45:00.0) Response from Jeremy at Thorlabs: We are working on correcting the spec sheet and description issue. For #3, since you are increasing the duty cycle a bit, I would suggest decreasing the current slightly, to 0.95A. kevinserg
(posted 2013-01-22 10:00:44.447) Hello, please, answer my questions about LED370E and LED2350P. Sorry for my English.
1) Can LED370E be used in pulsed regime? There is no pulsed regime description in LED370E data sheet. What is Peak Pulsed Forward Current for LED370E? Are there data for forward voltage vs current and output power vs current for LED370E?
2) Are there data for forward voltage vs current and output power vs current for LED2350P?
3) What is the minimum distance between LED2350P and print circuit board? Can I mount LED2350P close to PCB?
4) Please, recommend IC (integrated circuit) for pulsed regime of LED2350P with parameters: pulse=1uS, period=500uS, pulse current=1A.
5) There is mismatch (mistake?) for pulsed regime figure of LED2350P:
I peak pulsed=2A (in file "LED2350P-SpecSheet.pdf")
I peak pulsed=1A (in file "1353.pdf") Where is true? tcohen
(posted 2012-09-05 13:43:00.0) Response from Tim at Thorlabs: The LED3100P has gone obsolete and has no direct replacement. If you are looking for the supporting documentation for this LED, this can be found by searching this product number. If you have any questions on this product, please contact us at techsupport@thorlabs.com. user
(posted 2012-08-31 02:39:00.0) Why can't I find the 3100 nm led? tcohen
(posted 2012-06-22 09:16:00.0) Response from Tim at Thorlabs: 5V will damage this diode. Please check the spec sheet for the forward voltage of this LED (~1.15V at 50mA). To use 5V you would need to include a resistor based on the desired current and forward voltage of the LED. With a forward voltage of 1.15V and 5V DC supply, you can see the series resistor needed to induce 50mA of current is just (5V-1.15V)/50mA. We recommend using a constant current source for these products. The bare LED has a half viewing angle of 15 degrees and the power is ~7.5mW. This is a divergent source and not very high power. However, care must always be taken when introducing optical elements into a beam path and any concerns of safety should be addressed with your laser safety officer. matt968

(posted 2012-04-19 09:28:00.0) Response from Tim at Thorlabs: We do not have expected lifetime data for this LED. As always, you can prolong the life of your LED and reduce degradation by reducing the drive current and junction temperature. paul.lauria

(posted 2012-02-21 11:13:00.0) A response from Sean at Thorlabs:
Thank you for your feedback on the LED780E spec sheet. We will update the spec sheet with the correct plot as soon as the data is available. In the meantime, if you needed a normalized intensity curve for the LED780E, we have one on the catalog page located at http://www.thorlabs.com/catalogpages/V21/1345.PDF. Thank you for pointing out this error. lindsey.couvreur
(posted 2012-02-17 10:01:04.0) There is a mistake in LED780E data sheet: Typical LED591E Spectral Distribution appears instead. sharrell
(posted 2011-12-19 15:33:00.0) A response from Sean at Thorlabs: Thank you for your feedback. I am sorry that you had difficulty using our feedback form, and I have forwarded your comment to our webteam.
Regarding your feedback on our spec sheet plots, we will try to better integrate this information into our website, most likely using the "more info icon" you suggested. user
(posted 2011-12-19 14:51:07.0) Second try... your system said no key was found, would be nice to preserve the text if someone has an entry error...
Comment was that it is hard to get at the spectral plot provided on the Spec Sheets, please consider using the same method that is used for the Laser Diodes, where there is a "i" icon that triggers a pop up window with more data. It would work for me if that pop up gave a representative spectral plot. bdada

We are working on compiling the current vs output data for our LEDs and adding it to our website. Please email TechSupport@thorlabs.com so we can send you the data when we get it. user
(posted 2011-12-12 18:01:38.0) Is there data for current vs. output power for these LED's? In particular I'm interested in the LEDWE-15. Thank you. jjurado
(posted 2011-03-10 15:47:00.0) Response from Javier at Thorlabs to last poster: Thank you for submitting your inquiry. The UV-TOP LEDs have a rise time in the range 1-2 ns, which translates into a modulation frequency of 350 MHz to 175 MHz. Our LEDs for the visible and infrared range exhibit similar performance. Please contact Tech Support at techsupport@thorlabs.com for questions about a particular LED. user
(posted 2011-03-09 17:18:48.0) How fast can I modulate this LEDs? thanks Thorlabs
(posted 2011-01-19 10:18:43.0) Response from Javier at Thorlabs to ruelas: Thank you very much for submitting your feedback. We have reviewed the specifications and you are correct, the half-viewing angle spec for the LEDWE-50 is, in fact, 25 degrees. We will correct this information on the webpage accordingly. ruelas
(posted 2011-01-17 21:24:19.0) We have purchased several of the LEDWE-50 LEDs in the past and we have just noticed the viewing angle specification is inconsistent inconsistent; the webpage says the half-viewing angle is 50degrees, when it is actually 25 degrees, as specified in the catalog. Thorlabs
(posted 2010-08-20 10:37:02.0) Response from Javier at Thorlabs to smuehlen: Thank you for your feedback. The spectral distribution graphs are available on the spec sheets of our LEDs. I will send you a copy of the spec sheet of the LEDRGBE, which is also available here: http://www.thorlabs.com/Thorcat/16400/16400-S01.pdf smuehlen
(posted 2010-08-19 11:09:26.0) Are there any documents about the spectral distribution of the LEDRGBE as a function of the three applied voltages? This would be very helpful! Thorlabs
(posted 2010-08-06 18:10:50.0) Response from Javier at Thorlabs to sgourley: Thank you for your feedback. The typical full width at half maximum (FWHM) value for this diode is 100 nm. sgourley
(posted 2010-08-06 16:01:16.0) What is the bandwidth of the LED1300E? We have a replacement 1300nm design that is in the 50uW power level. We actually will need to mount in a TO-46 hole but appears it may be possible with this LED.
Thanks,
Sam G Thorlabs
(posted 2010-07-29 09:25:59.0) Response from Javier at Thorlabs to Vincent: Thank you for your feedback. We are currently looking into this for you. I will contact you directly once we have the details. vincent.thominet

(posted 2009-11-05 12:41:39.0) A response from Lou at Thorlabs to abytas:
The LED341 is mid UV light emitting diode. It will emit light at approx 340nm (+/- 10nm) The window of the LED is a flat window and is not a lens. For your application the LED might proof best operation to involve a laser diode driver. You will have precise control over the light being emitted (power).
Im not sure how you want to use the emitting light. The light will diverge at about 15 degrees from the emitter. Typically such light would need to captured by collimation and focusing. But the type of optics required would depend on you use. abytas

LEDMT1E Electrical Schematic
- USB-Powered Mount for LEDs in T-1 3/4 Packages
- Options with Built-In 51 Ω or 62 Ω Current-Limiting Resistor for Different Electrical Requirements
- External SM05 (0.535"-40) Mounting Thread
- Includes Micro-B USB to USB Type-A Cable for Power LED Module
These USB-Powered LED Mounts provide both power and a mounting socket for our unmounted LEDs in T-1 3/4 packages within a single compact housing. Because of the varied electrical requirements, we offer the LED mounts with either a 51 Ω or 62 Ω current-limiting resistor. The module is powered via the micro-B USB port on the back of the housing which can be connected to a USB power source or PC via the included USB to micro-B USB cable. The housing exterior features external SM05 (0.535"-40) threading which can be used to integrate these mounts with a cage system or SM05-threaded component.
When mounting an LED, use the engraving on the housing to determine the appropriate length to cut the leads (see drawing to the right). Insert the LED with the anode lead going into the socket indicated by a (+) sign and the cathode into the socket indicated by a (-) sign. Use light force to mount the LED as excessive force may bend the electrode leads.
These powered mounts offer a fixed resistance and input voltage; choosing the appropriate mount for your LED will minimize damage to the LED. In general, a mount with a lower resistance value will increase the forward current available to the LED and proportionally increase the optical output power. However, the forward current must not exceed the maximum current of LED as this can cause permanent damage to the LED. The minimum mount resistance (R) recommended to use a desired LED is given by the following equation:
where the input voltage of the mount (VI,Source) is 5 V and the typical forward voltage (VF,Typ) and maximum forward current (IF,Max) are properties of each LED. Please consult the specifications of your LED for these values.

The LEDMF LED Mount is designed to hold any of Thorlabs' TO-18R packages directly or our T-1 3/4 or TO-18 packages using one of the included adapter rings (Ø4.7 mm adapter for TO-18 or Ø5 mm adapter for T-1 3/4). The LED is secured in the mount with a top-located cap screw with a 5/64" (2 mm) hex. The L-shaped mount has a counterbored through hole suitable for an 8-32 (M4) cap screw so that the LEDMF can be attached to a Ø1/2" Post.
The S05LEDM and S1LEDM LED Mounts are SM05 (0.535"-40) and SM1 (1.035"-40) threaded, respectively. They are designed to hold any of Thorlabs' TO-18, TO-39, TO-46, or T-1 3/4 packages using the included adapter rings. The external threading on these mounts allows them to be used in a wide variety of SM05- or SM1-compatible optomechanics.
To aid in threading the retaining ring into the mount or in threading the mount into a mating component, we recommend using our selection of spanner wrenches. The SPW801 Adjustable Spanner Wrench can be used to thread LED retaining rings into the mount and the mount into a mating component. Alternatively, the table to the right also lists the compatible fixed spanner wrench for each mount.
