UV LED with Aspheric Glass Lens
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 4.4 µm. These unmounted LEDs are available epoxy-encased in T-1 3/4 packages or in a variety of TO-can style housings, including TO-18, TO-46, TO-39, Ø9 mm, and TO-18R. A selection of the UV LEDs have ball lenses that focus the output into a narrow viewing half angle of no more than 7.5°, while the other LEDs that are in TO-can style packages are offered with flat windows, glass covers, glass lenses, or parabolic retroreflectors.
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. An unmounted LED with a center wavelength of 4400 nm features a parabolic reflector that reduces the output divergence angle. See the Collimation tab for more information on collimating the light from an LED. 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. |
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:
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.
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.

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.

Collimating light from an LED or other large, incoherent source can be a surprisingly challenging task. The emitter’s size and the collimating lens’ focal length and numerical aperture (NA) all influence the characteristics of the collimated beam. It can also be hard to know when the lens is positioned optimally. In this video, two lenses with different NAs and focal lengths are used to demonstrate a couple of collimation approaches. In addition, the emerging image of the emitter and other typical features of beams provided by collimating lenses are explored.
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.

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.

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.
