Thorlabs' collimated LED assemblies can be easily connected to standard and epi-illumination ports on most readily available commercial microscopes, including Olympus, Leica, Nikon, and Zeiss. Each collimated LED consists of a mounted LED and a lamphouse-port-compatible housing that contains an AR-coated aspheric collimation optic (see the Specs tab for details). If the wavelength or output power you require is not sold on this page, our mounted LEDs and Solis^® High-Power LEDs are available in additional wavelengths and output powers.

Note: Please ensure your microscope is configured to directly accept an external light source. Some microscope assemblies have a permanently installed illuminator or may be otherwise incompatible with the LED light sources below.

The collimation of the beam can be adjusted by changing the position of the aspheric lens with respect to the LED. Interchanging LEDs is easy; simply unscrew one LED from the housing and replace it with a different mounted LED (sold separately). We also offer collimation packages, which can be purchased separately from these LEDs.

The approximate total beam power through the collimation adapter is given in the tables below and on the Specs tab. The actual power at the sample plane will be lower due to losses specific to the optical set up of the microscope. If you wish to measure the power at the sample plane for your particular microscope setup, Thorlabs also offers a microscope slide power meter sensor.

Like our mounted LEDs, the package of these collimated LEDs is in direct contact with the heat sink to provide excellent thermal management. This minimizes the degradation of optical output power caused by increased LED temperatures. Please see the Stability tab for information on the stable output intensity of these collimated LEDs. Additionally, our M365LP1, M385LP1, and M405LP1 LEDs feature a higher power output and are mounted to a larger Ø57.0 mm heat sink to increase heat dissipation and thermal stability.

For microscope applications requiring compatibility with SM1 (1.035"-40) threading, our mounted LEDs (sold separately) can be collimated using a Ø1" lens and lens tubes. This collimation method also allows for a smaller beam size than the collimators on this page. Please see the Collimation tab on our Mounted LEDs presentation for a detailed item list and instructions.

Driver Options
Thorlabs offers six drivers compatible with these LEDs: LEDD1B, UPLED, DC40, DC2200, DC4100, and DC4104 (the latter two require the DC4100-HUB). The UPLED, DC40, DC2200, DC4100, and DC4104 drivers are capable of reading the current limit from the EEPROM chip of the connected LED and automatically adjusting the maximum current setting to protect the LED. See the LED Drivers tab for specifications and comparison between the drivers.

Specifications for the LEDs without collimating adapters are given in this table. Please see the second table on this tab for specifications pertaining to the LED with the collimating adapter attached.
Due to variations in the manufacturing process and operating parameters such as temperature and current, the actual spectral output of any given LED will vary. Output plots and nominal wavelength specs are only intended to be used as a guideline.
For LEDs in the visible spectrum, the nominal wavelength indicates the wavelength at which the LED appears brightest to the human eye. For UV and IR LEDs, the nominal wavelength corresponds to the peak wavelength. The nominal wavelength for visible LEDs may not correspond to the peak wavelength as measured by a spectrograph.
For the bare LED. See the table below for total beam power with the collimation package.
Our 365 nm to 405 nm LEDs radiate intense UV light during operation. Precautions must be taken to prevent looking directly at the UV light and UV light protective glasses must be worn to avoid eye damage. Exposure of the skin and other body parts to the UV light should be avoided.
These LEDs have a higher output power (see tables below for total beam power) and are mounted to a Ø57.0 mm heat sink for increased heat dissipation.

LED Lifetime and Long-Term Power Stability

One characteristic of LEDs is that they naturally exhibit power degradation with time. Often this power degradation is slow, but there are also instances where large, rapid drops in power, or even complete LED failure, occur. LED lifetimes are defined as the time it takes a specified percentage of a type of LED to fall below some power level. The parameters for the lifetime measurement can be written using the notation B_XX/L_YY, where XX is the percentage of that type of LED that will provide less than YY percent of the specified output power after the lifetime has elapsed. Thorlabs defines the lifetime of our LEDs as B₅₀/L₅₀, meaning that 50% of the LEDs with a given Item # will fall below 50% of the initial optical power at the end of the specified lifetime. For example, if a batch of 100 LEDs is rated for 150 mW of output power, 50 of these LEDs can be expected to produce an output power of ≤75 mW after the specified LED lifetime has elapsed.

Optimized Thermal Management

The thermal dissipation performance of these collimated LEDs has been optimized for stable power output. The heat sink is directly mounted to the LED mount so as to provide optimal thermal contact. By doing so, the degradation of optical output power that can be attributed to increased LED junction temperature is minimized (see the graph to the right).

Pin Connection - Male

The diagram to the right shows the male connector of the collimated LED assembly. It is a standard M8 x 1 sensor circular connector. Pins 1 and 2 are the connection to the LED. Pin 3 and 4 are used for the internal EEPROM in these LEDs. If using an LED driver that was not purchased from Thorlabs, be careful that the appropriate connections are made to Pin 1 and Pin 2 and that you do not attempt to drive the LED through the EEPROM pins.

To fully support the max optical power of the LED you intend to drive, ensure that the max voltage and max current of the driver are equal to or greater than those of the LED.

Automatically limits to LED's max current via EEPROM readout.
The DC4100 and DC4104 can power and control up to four LEDs simultaneously when used with the DC4100-HUB. The LEDs on this page all require the DC4100-HUB when used with the DC4100 or DC4104.
LEDs with maximum current ratings higher than the driver's maximum current output can be driven, but will not reach full power. See the Specs tab for the maximum current rating of each LED.
The DC40 LED Driver is designed to automatically select the appropriate current/voltage combination for the LED on this page. Please note that the maximum current and forward voltage are interdependent; the DC40 driver cannot drive an LED with a 14.0 V forward voltage at 4.0 A. Please see the full web presentation for more information.
The collimated LEDs sold below are compatible with the LED2 Terminal.
LEDs with forward voltage greater than the driver's maximum forward voltage cannot be driven. See the Specs tab for the forward voltage specification of each LED.
Small Signal Bandwidth: Modulation not exceeding 20% of full scale current. The driver accepts other waveforms, but the maximum frequency will be reduced.
The MCWHL8-C LEDs may not turn off completely when modulated at frequencies above 5 kHz, as the white light is produced by optically stimulating emission from phosphor.

Hello. My name is YeonJae Yoo, who works for LG Chem in Korea. I am writing this email because I have an inquiry regarding the purchase of a 365nm wavelength LED. If I buy this product, will the 365nm LED collimated beam come out without any other accessories? I want to know if I need to purchase another driver. Please reply by e-mail.

Hi Ms. Yoo, thank you for your enquiry. I will personally reach out to you to provide more information.

Dear sir, I am looking for collimated LED light sources which are internally or externally SM2 threaded (like Solice LEDs). This would be very universal and convenient for integrating them with other thorlabs optics. They can be surely compatible with microscopes using, for example, SM2A13. I have a Solice LED for this purpose but need lighter one such as MCWHL6-C1. Alternatively, it would be great for you to provide adapters to fit MCWHL6-C1 to SM2 threaded parts. Thanks.

MKiess (posted 2021-03-25 11:13:07.0)

Thank you very much for this feedback. You can use a MCWHL6 LED in combination with a SM2F32-A, adjustable collimation adapter for Ø2" (Ø50 mm) Optics for this purpose. The MCWHL6 is the same LED that is also used for the MCWHL6-C1. You can screw the SM2F32-A collimator directly to this LED. The collimator has an internal SM2 thread for further integration.

Patrick Lee (posted 2021-03-09 11:23:47.873)

Hi, I am interested in MCWHL6-C1. I plan to use it as a collimated light source to shine on a test object, in order to cast a shadow on a diffuser glass. A camera is placed at back of diffuser to pick up the shadow. a) what is divergence output ? b) will shadow be sharp ? c) any recommendation for power supplier ? Thank you.

MKiess (posted 2021-03-11 08:59:36.0)

Dear Patrick, Thank you for your inquiry. A suitable LED driver for the MCWHL6-C1, is the LEDD1B or the DC2200. The divergence and sharpness of the shadow depends on your overall optical system of diffuser and lenses used, as well as the camera parameters. I have contacted you directly to discuss the details.

Hi, I am interested in using the MCWHL6-C5 to replace a 12V100W halogen lamphouse on my Nikon microscope. Roughly speaking, would the total output (477 mW) be comparable to the total output of the halogen bulb?

MKiess (posted 2021-02-15 11:03:51.0)

Thank you very much for your inquiry. It depends on what the exact output power of the halogen lamp is. I assume that it will be a little higher than that of this LED. Cold white, LEDs with higher output power, which can also be connected to the Nikon microscope with corresponding collimators or adapters (As can be found, for example, under the following link.: https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=8706) would be the SOLIS-1C and the MCWHLP1. I have contacted you directly to discuss the exact requirement together.

Hajun Song (posted 2020-11-09 01:50:49.14)

I want to use this model as a flash lamp for the high speed camera. What is the eletrical bandwidth of the laser? Is it possble to modulate the LD as a short pulse modulation? How narrow?

wskopalik (posted 2020-11-09 10:39:33.0)

Dear Hajun, Thank you very much for your feedback. Unfortunately we do not have any data about the rise time of the M780L3-C1. Usually the bandwidth of LEDs is limited by the driver electronics rather than by the LED itself. So the specifications of the driver would need to be considered in most cases. A good assumption for the rise time of an LED without phosphor like the M780L3-C1 is the range of at least 100 ns. This corresponds to an 3dB bandwidth of 3.5 MHz. Phosphor-converted LEDs (e.g. for white light) can however be considerably slower than that. I will contact you directly so we can talk about your requirements in more detail.

This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry. The collimated LED light sources for Olympus BX and IX microscopes can be directly attached to the epi-illumination port of these microscopes. For the transmission-illumination port we might be able to offer a suitable collimator as a special. I have contacted you directly to provide further information and to discuss the issue in more detail.

Hello! The LED M455L3 would suite my application, I'm looking for possibilities to collimate it correctly ideally in a small beam with low divergence.. I do not need it for microscopy. A 5 cm diameter beam is quite big but if the collimation is good I could resize it with further optics, so the first question is "which is the divergence of the beam after collimation in the product M455L3-C1"? Second question, are there other possibilities to collimate the M455L3 LED in for example a < 1.5 cm beam with divergence < 5°? How much power loss should it cause?? Thanks in advance!!!

jvigroux (posted 2014-04-10 10:10:14.0)

A response from Julien at Thorlabs: Thank you for your inquiry! The divergence of the M455L3-C1is typically of about 3° and in best case slightly less than 2°, so that in principle it would be possible to resize the beam after the 2" output. By using another collimating lens than the standard 2" diameter 40mm focal length, one can further reduce the output collimated beam. I will contact you directly to discuss the requirements in termsof powe and divergence in order to see which option would work best in your case.

Hello, I have bought the MCWHL5-C1 and I would like to mount it externally on a bar to a device. Sadly I am not sure which mount I should best use where I can put the device in and connect it to the bar with screws. Can you recommend me a device from your catalogue which is best suited for that? Thanks in advance

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. To mount our collimated LED light sources you can use a lens tube slip ring SM1RC: https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=1533&pn=SM1RC#2714. I will contact you directly with more detailed information.

I am very interested in using an LED light source in place of a 100 watt halogen lamp -- in the EPI illuminators of my (6) Nikon Optiphot 150 microscopes. We are primarily using brightfield and DIC imaging. Would your mounted LEDs (probably cool white or green) work in this application? Thanks, Mike Hunter

A response from Thomas at Thorlabs. Thank you very much for your inquiry. At the moment we don’t have an adapter which is suitable for the Nikon Optiphot 150 microscopes. I will contact you directly to check if we can find a solution.

Is it possible to mount collimated LEDs in a standard SM1-mount?

tcohen (posted 2013-03-14 13:37:00.0)

Response from Tim at Thorlabs: The back end of these have 1.2” diameters and can be used with an SM1RC slip ring. The beam diameters produced by these larger focal length lenses would overfill an SM1 thread. If you are looking to confine it to this size an alternative would be to use the mounted LED without the collimating optic, (this is the M***L2 series and can be purchased separately) and then use a 1” diameter lens with an adjustable length lens tube for alignment. We have a typical setup to this end on our “Application” tab on the M***L2 series page.

A response form Julien at Thorlabs: Thank you for your inquiry! As far as I know, DIC usually uses polarized light sources. If this is the cas ein your setup, the LEd would not work because of the light being unpolarized. The use of an extra polarizer after the LED would imply a strong power reduction as well as a relatively high instability of the output power. I will contact you directly to discuss the details of your setup in order to see which light source could be used.

Hi, We are interested in buying an LED to replace the lamp of DIC to use it in multicolor imaging. Wavelength range we are looking for is between 670 and 750nm. Can you suggest if 260mW of 735nm LED is good enough for DIC imaging? Has anyone used it for DIC? Babu

A response from Julien at Thorlabs: Thank you for your feedback! the suggested adapters are by no mean the only solution and based on the details of your setup, some other configuration might indeed improve the power density or the homogeneity. I will contact you directly to discuss the details and see which solution would be the most adapted.

g.raffy (posted 2012-01-23 09:12:12.0)

A collimated beam with 50mm diameter will be clipped by the back aperture of the objective in an IX microscope (~10mm), loosing most of the available power of the LED. Am I wrong? Why not proposing an alternative lens that lets all the light entering the objective? I really need all the power... Ideally, if the lens to LED distance is settable, then one could choose between power density and uniformity of illumination.

Response from Buki at Thorlabs: Thank you for your interest in our MCWHL2-C1 and for taking the time to use our feedback tool! These mounts are designed to fit on the standard and epi-illumination ports for Olympus BX and IX microscopes. The exact compatibility will depend on whether the transmitted lamp housing on your desired Olympus microscope has the same port-style as the BX and IX. Please contact TechSupport@thorlabs.com if you have further inquiries.

mzlin (posted 2011-09-02 12:01:15.0)

Can anyone verify that the Olympus mounts will fit in place of the transmitted lamp housing too (i.e. the same mount will work for transmitted as for fluorescence)? We have not gotten our scope yet so cant measure ourselves. Thanks.
