LEDs are compact, energy efficient light sources that are available with or without beam shaping optics. General information that allows for a quick comparison of the available LEDs can be found in the tables below, while the complete set of specifications and spectrum of a particular LED can be viewed by clicking on the red "Documents Icon" next to the item number and then opening the Spec Sheet link. The Characterization Tab describes sample methods and equipment for characterization of the majority of the LEDs offered on this page. The following LEDs are sold in packages of five: LED465E (465 nm), LED525E (525 nm), LED528EHP (525 nm), LED591E (590 nm), LED630E (639 nm), LED780E (780 nm), LED870E (870 nm), LED940E (940 nm), and LEDRGBE (620/515/480 nm).

Thorlabs offers post-mountable and SM-threaded passive mounts, as well as a socket for LEDs (see below).

Collimation
Because the LEDs shown here have significant divergence, the output light frequently needs to be focused in order to send it to experimental setups. For our unmounted LEDs in the 400 - 1600 nm spectral range, we generally recommend our family of Aspheric Condenser Lenses, which make the output less divergent and are available uncoated or AR coated. Our LEDs in the 1600 - 4600 nm spectral range feature parabolic reflectors that reduce the divergence angle. To focus the output of our UV LEDs or to discuss other options, please contact Technical Support.

Thorlabs also manufactures Collimated Mounted LEDs and collimated LEDs for microscopes.

If you do not see the an LED with the wavelength/color desired, please contact Technical Support, and we will endeavor 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 Fiber-Coupled Compact Spectrometer connected to a computer is used to measure the spectral response of each LED in the UV/visible wavelength range (200 - 1000 nm; for LEDs emitting in NIR, use the OSA202). 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 SMA connectors attached to the spectrometer.

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 is rotated on an axis perpendicular to the axis along which the emitted light intensity was the greatest. Goniometric rotation of the LED is achieved by mounting the LED on a post attached to a CR1-Z7 Motorized Rotation Stage so that the rotation axis goes through the light emitting surface of the LED. The CR1-Z7 stage is controlled by a TDC001 T-Cube Servo Motor Driver, while the LED is powered by an LD1255R Laser Diode Driver. The radiated light is detected using either a Si or Ge Photodetector, DET36A or DET30B 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 CR1-Z7 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 is 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 CPS180 Laser Diode Module. The output of the photodiode can be amplified and measured using our PDA200C Benchtop Photodiode Amplifier.

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.

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?

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.

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.

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.

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.

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.

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

Are there any documents about the spectral distribution of the LEDRGBE as a function of the three applied voltages? This would be very helpful!

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

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.

  • The LEDRGBE is not compatible with the LEDMF, S05LEDM, and S1LEDM, as the four pins prevent the retaining ring from holding the LED in place.

The LEDMF LED Mount is designed to hold any of Thorlabs' T1-3/4 or TO-18 packages using one of the included adapter rings (Ø4.7 mm adapter for TO-18 or Ø5 mm adapter for T1-3/4). 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 T1-3/4 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.
