Each uncollimated, mounted LED consists of a single high-power LED with multiple emitters that has been mounted to the end of a heat sink. The heat sink has internal SM1 (1.035"-40) threads and has the same external diameter (1.20") as an SM1 lens tube, which makes it easy to integrate with other Thorlabs components. The integrated EEPROM chip in each LED stores information about the LED (e.g., current limit, wavelength, and forward voltage) and can be read by Thorlabs' DC2100 and DC4100 LED Controllers. For more information about LED drivers, including the basic LEDD1B driver, see the LED Drivers tab.

Optimized Thermal Management
These high-power mounted LEDs possess good thermal stability properties, eliminating the issue of degradation of optical output power due to increased LED temperature. For more details, please see the Stability tab.

Broadband LED Option
The MBB1L3 mounted LED has been designed to have relatively flat spectral emission over a wide wavelength range. It offers a 280 nm FWHM bandwidth, while the 10 dB bandwidth ranges between 470 nm and 850 nm. For more information on the spectrum of this broadband source, please see the table to the right.

Collimation & Microscope Adapters
Collimation adapters are available that contain an AR-coated aspheric lens and are designed to mate to the epi-illumination ports on Leica DMI, Nikon Eclipse, Olympus IX/BX, and Zeiss Axioskop microscopes. See below for more details. Additionally, Thorlabs offers mounted LEDs with microscope adapters pre-attached. Please see the Collimated LED page for more information.

Multi-LED Source
A customizable multi-LED source may be constructed using our mounted high-power LEDs and other Thorlabs items. This source may be configured for integration with Thorlabs' flexible SM1 Lens Tube Systems, 30 mm Cage Systems, and the microscope adapters sold below. Please see the Multi-LED Source tab for a detailed item list and instructions.

Thorlabs also offers integrated, user-configurable 4-Wavelength High-Power LED Sources.

Driver Options
These LEDs can be powered with a Thorlabs LEDD1B, DC2100, DC4100, or DC4104 LED driver (the latter two require the DC4100-HUB). See the LED Drivers tab for compatibility and driver features. The LEDD1B is capable of providing LED modulation frequencies up to 5 kHz, while DC2100, DC4100, and DC4104 can modulate the LED at a rate up to 100 kHz. In addition, the DC2100, DC4100, and DC4104 drivers are capable of reading the current limit from the EEPROM chip of the connected LED and automatically adjusting the max current setting to protect the LED.

Relative Power

The actual spectral output and total output power of any given LED will vary due to variations in the manufacturing process and operating parameters, such as temperature and current. Both a typical and minimum output power are specified to help you select an LED that suits your needs. Each mounted high-power LED will provide at least the minimum specified output power at the maximum current. In order to provide a point of comparison for the relative powers of LEDs with different nominal wavelengths, the spectra in the plots below have been scaled to the minimum output power for each LED. This data is representative, not absolute. An excel file with normalized and scaled spectra for all of the mounted high-power LEDs can be downloaded here.

Optimized Thermal Management

The thermal dissipation performance of these mounted 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).

Collimating the LED

Thorlabs' mounted high-power LEDs can be easily collimated with Ø1" components using the items listed in the table below. Some of the applications of the collimated LEDs include custom imaging systems, microscope illuminators, or projectors. Please be careful to follow proper optics handling procedures (Optic Handling Tutorial) during the following steps.

  • While these components are SM1 threaded, we recommend our adjustable spanner wrench due to the steep curvature of the aspheric condenser lens.
  • -A and -B refer to the type of AR coating on the lens. Any LED with nominal wavelength less than 735 nm would require the -A coating, and any LED with nominal wavelength of 735 nm and above would require the ‑B Coating.
  1. Adjustable length lens tube assembly:
    1. Description: The adjustable length lens tube (SM1V05) allows one to accurately control the exact working distance of the lens while collimating the LED. The SM1-threaded (1.035”-40) SM1V05 comes with a locking nut and a retaining ring. For customers concerned with the homogenity of the beam, the AR-coated aspheric condenser lens with diffuser (ACL2520-DG6-A or ACL2520-DG6-B) is a good option.
    2. Setup: By the end of this step, the lens will rest on top of one retaining ring (SM1RR) and be secured in place by another retaining ring placed on top of it. To begin, use the spanner wrench (SPW801) to turn the included retaining ring in the adjustable length lens tube so that it is closer to the inside lip of the tube. Then, carefully place the lens inside the adjustable length lens tube with the curved side facing away from the male-threaded end of the tube. Finally, secure the lens in place with another retaining ring (SM1RR) using the spanner wrench.
  2. Thread the male end of the SM1L03 lens tube into the female end of the LED and gently tighten it.
  3. Partially thread the male end of the SM1V05 adjustable length lens tube assembly into the female end of the SM1L03-LED assembly.

  5. Obtaining a well-collimated beam:
    1. Description: A well-collimated beam has minimal divergence and will not converge at any point in the beam path. Be advised that due to the nature of the output from the LED (high emitter surface area), the beam cannot be perfectly collimated. Please refer to the table below for divergence data.
    2. Setup: Power on the LED and check to see if it is properly collimated. It is easiest to check that the beam is collimated by noting the changes in the beam diameter over a range of about 1” to 2 feet away; then tighten or loosen the adjustable length lens assembly and check again. Do this until the least divergent, non-converging, homogenous beam is obtained. The beam should be somewhat circular in diameter, may have a slightly polygonal shape, and should not be a clear image of the LED itself.
    3. If you see an image of the LED, this means that the lens is not close enough to the LED. Tighten the SM1V05 until the image blurs and becomes homogenous – this is the point of collimation. If the lens needs to be closer to the LED, use only one retaining ring to secure the lens in the SM1V05 so that the lens will rest on the inside lip of the SM1V05 adjustable length lens tube.

  6. Once the proper collimation position of the lens has been found, loosen the SM1V05 assembly by about ¼ to ½ turn, rotate the external locking nut until it is flush with the edge of the SM1L03 lens tube, and gently tighten both the assembly and the locking nut by ¼ to ½ turn (there should be slight resistance; do not over tighten). This will lock the collimation position in place.

Multi-LED Source Coupled to Microscope Illumination Port

Creating a Custom Multi-LED Source for Microscope Illumination

Thorlabs offers the items necessary to create your own custom multi-LED light source using two or three of the mounted LEDs offered below. As configured in the following example, the light source is intended to be used with the illumination port of a microscope. However, it may be integrated with other applications using Thorlabs' flexible SM1 Lens Tube and 30 mm Cage Systems. Thorlabs also offers integrated, user-configurable 4-Wavelength High-Power LED Sources.

Design & Construction

First, light will be collimated by lenses mounted in lens tubes. Dichroic mirrors mounted in kinematic cage cubes then combine the output from the multiple LEDs. The mounted LEDs may be driven by LEDD1B Compact T-Cube LED Drivers (TPS001 T-Cube Power Supplies are sold separately). The LEDD1B LED Drivers allow each LED's output to be independently modulated and can provide up to 1200 mA of current. Please take care not to drive the LED sources above their max current ratings.

When designing your custom source, select mounted LEDs from below along with dichroic mirror(s) that have cutoff wavelength(s) between the LED wavelengths. The appropriate dichroic mirror(s) will reflect light from side-mounted LEDs and transmit light along the optical axis. Please note that most of these dichroic mirrors are "longpass" filters, meaning they transmit the longer wavelengths and reflect the shorter wavelengths. To superimpose light from three or more LEDs, add each in series (as shown below), starting from the back with longer wavelength LEDs when using longpass filters. Shortpass filters may also used if the longer wavelength is reflected and the shorter wavelength is transmitted. Sample combinations of compatible dichroic mirrors and LEDs are offered in the three tables below.

It is also necessary to select an aspheric condenser lens for each source with AR coatings appropriate for the source. Before assembling the light source, collimate the light from each mounted high-power LED as detailed in the Collimation tab. For mounting the aspheric lenses in the SM1V05 Lens Tubes using the included SM1RR retaining rings, we recommend the SPW801 Adjustable Spanner Wrench. A properly collimated LED source should have a resultant beam that is approximately homogenous and not highly divergent at a distance of approximately 2 feet (60 cm). An example of a well-collimated beam is shown on the Collimation tab.

After each LED source is collimated, thread the SM1V05 Lens Tubes at the end of each collimated LED assembly into their respective C4W Cage Cube ports using SM1T2 Lens Tube Couplers. Install each dichroic filter in an FFM1 Dichroic Filter Holder, and mount each filter holder onto a B4C Kinematic Cage Cube Platform. Each platform is then installed in the C4W Cage Cubes by partially threading the included screws into the bottom of the cube, and then inserting and rotating the B4C platform into place. Align the platform to the desired position and then firmly tighten the screws. To connect multiple cage cubes and the microscope adapter, use the remaining SM1T2 lens tube couplers along with an SM1L05 0.5" Lens Tube between adjacent cage cubes. Finally, adjust the rotation, tip, and tilt of each B4C platform to align the reflected and transmitted beams so they overlap as closely as possible.

If desired, a multi-LED source may be constructed that employs more than three LEDs. The limiting factors for the number of LEDs that can be practically used are the collimation of the light and the dichroic mirror efficiency over the specified range. Heavier multi-LED sources may be supported with our Ø1" or Ø1.5" Posts.

Dear Sir or Madame, Can you send me the ray file for Zemax for the LED MWWHL3 Warm White 3000K? I could not quite identify which LED is actuall mounted. I would like to simulate the combination of this LED with the COP1-A in Zemax and combine this with some additional optical elements. Thank you in advance for your help! Kind regards, Jan Ellinghaus

Dear Sir or Madam, I have a question concerning the mounted LED system you supply. We are using it as a BIAS illumination source in a measurement setup. I was wondering what the EEPROM on the PCB is for. Is it in any way affecting the current supply of the LED? In particular, is it possible that it creates some noise on the current supplying the LED? Thank you in advance for your help! Best regards, Jan Haschke

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. Our Mounted High Power LEDs are all equipped with an EEPROM where the operating parameters are stored. The LED drivers DC2100, DC4100 and DC4104 read out the EEPORM and set the maximum operating current to the stored value. This way a current overload can be avoided. The driver LEDD1B is not able to read out the EEPROM and the current limit has to be set manually. The EEPROM will not cause noise to the current supply. I will contact you directly with more detailed information.

A response form julien at Thorlabs: Than you for pointing this out. We corrected the presentation on our website so that now the wrench recommended is the SPW801. We will send you a replacement for the lens together with the new case.

One other thing: On the application page where it explains how to collimate the LED, it says to use a SPW602 spanner wrench to secure the aspheric lens with one retaining ring on each side. I did this, and the SPW602 carved a circle on the front surface of the lens. Please change this text to instruct people to use a different spanner, so they don't inadvertently scratch their collimating lens.

Hi: I have a minor issue to relay about the packaging of the mounted LEDs. I bought an M735L3 late last week and received it today. The plastic case it comes in is not well designed or built. Specifically, the red latch on front broke off while I was trying to figure out how to open the case. And it took two of the black plastic hinge-posts with it, so even when I put the latch back on the case, the case won't stay shut anymore. It seems silly to provide these in a hard shell case if the latch can't withstand a bit of force from a novice case-opener.

Response from Jeremy at Thorlabs: Is your power supply a voltage source or is it a current source? It is highly recommended that you drive these LEDs with a current source instead. If you used a 5V constant voltage source (@ 3A), then you will most likely be injecting 3A of current into this LED and thus destroyed it (max. current for MCWHL2 is 1.6A). Please note that the typical forward voltage for the MCWHL2 is only about 3.5V. It could also be that you have not connected this correctly. I will get in contact with you directly to check on the details on your setup.

Hi, I just recieved the MCWHL2 LED. I control it by a DC power supply. I set the voltage limit to ~5V and tried to rise the current, but the LED doesn't seem to be working. Am I doing something wrong? (the DC supplier can deliver up to 3A)

Hello Thorlabs. I am using the 385 nm LED and I need to know its on-off switching time, particularly its off time i.e. when you turn it off, what is the extinction time of the after glow. Even if this is not known precisely, as order of magnitude value would be very useful.

A response from Julien at Thorlabs: Dear HongYang, thank you for your inquiry! The curve displayed on our website is aimed at showing the effect of long term thermal stabilization, ie. heat transfer from the LED chip and PCB to the heat sink. Should the thermal exchange channel be poor, it can be that the temperature of the LED will settle at a too high temperature, which would lead to the situation displayed by the curve "LED with poor thermal management". The time scale for this effect is indeed in the seconds range and the curve was plotted accordingly, which can give the impression that the rise time is slow. This rise time is however much shorter than visible on this curve and is typically of a few 10's nanoseconds. The main limitation in this case is the capacitance of the LED and thermal effects as plotted on the aforementioned curve will only be relevant at on a much longer time scale and much lower in magnitude than the capacitance related limitation of the rise time.

Posted Date: 2012-07-16 03:08:26.0
The figure in the tab 'Stability' shows that the rise time of these LEDs is several seconds. So does it mean that LED cannot be fully charged when modulated at a high frequency? If so, that will introduce instability to the power in that situation, I suppose. Thanks a lot. Hongyang.

A response from Julien at Thorlabs: Thank you for your inquiry! The radiation characteristics of the LED, which corresponds to the variation of the emitted intensity with the angular departure from the optical axis, is plotted for all our LED's in the mfg spec sheets. Those spec sheet can be downloaded by clicking on the red document icon next to the product number of the LED.

A response from Julien at Thorlabs: thank you for your inquiry! the 500mA that are specified by the manufacturer of the LED in the MFG spec sheet apply only for the bare LED. Due to the fact that the LED is mounted on a large heat sink and that the thermal coupling to it is very good, the LED can be used in constant mode at currents up to 700mA.

A response from Julien at Thorlabs: Thank you for your inquiry! The approach you intend to use is unfortunately only partially possible. The problem is that the voltage drops across the LEDs will add up when they are connected in series. The specified operating voltage for this LED is 6.8V. As the compliance voltage of the LEDD1B is typically 12V, you will be only able to connect a maximum of two LEDs in series, unless you reduce drastically the current. I will contact you directly to discuss your application and see which approach is the best suited for your application.

*** Response from Javier at Thorlabs to skooi: Thank you very much for contacting us. The divergence of these mounted LEDs is in the order of 1 degree. The large, thick condenser used in this assembly generates a circular output beam, rather than a projection of the LED emitters. This has not been my experience at all. The divergence of our M660L2 is on the order of 3 and it is definitely imaging the LED, and not a uniform circular beam spot.

Response from Javier at Thorlabs to denis.battarel: Thank you for submitting your inquiry. There are a couple of options. You can use the LEDD1B driver, which has a maximum output of 1200 mA, or you can opt for the DC2100, whose maximum output current is 2000 mA. Both of these drivers can be operated in constant current mode, trigger mode, and modulation mode. Regarding the condenser lens, we would recommend using the ACL2520. Its diameter is 25 mm, so it is compatible with our SM1 lens tubes.

A response from Adam at Thorlabs to Michael: Typically LEDs are run at 5V or 12V. Using a voltage higher than 1V will not damage the LED if you can limit the amount of current reaching the device. LEDs are current run devices and will be damaged beyond repair if drive them with too much current. The M405L1 cannot be driven above 1000mA.

Response from Laurie at Thorlabs to atashtoush: To modulate the MBLED you will need the LEDD1 T-Cube LED driver and a TPS001 15 V power supply. You will need to provide your own signal generator with the following requirements: Minimum Strobe Pulse Width: 50 µs Strobe Turn-On / Turn-Off Time: <25 µs. The maximum flash rate obtainable with the LEDD1 with full 100% modulation will be around 3 kHz with a maximum strobe effect up to 10 kHz. If you need to modulate at higher rates you would need to consider a laser driver. Depending on the driver, you can indirectly modulate to about 250 kHz. Above that value you need to RF modulation directly into the LED anode.

Two AR coating ranges (350 - 700 nm and 650 - 1050 nm) and four different collimator housings are available. Each housing is designed to mate to the illumination port on selected Olympus*, Leica, Nikon, or Zeiss microscopes. Compatible microscopes are listed in the Collimation Adapter Selection Guide table below.

The LED sources described above can be fitted to the collimators by using an SM2T2 Coupler and SM1A2 Adapter (not included) as shown in the image at right. This assembly can be easily adapted to different LED sources by unscrewing the LED housing.

If compatibility with SM1 (1.035"-40) threading is preferable to compatibility with a microscope for your application, our mounted LEDs can be collimated using a lens and lens tubes. Please see the Collimation tab for a detailed item list and instructions.

* Please note that due to the optical design of the transmitted lamphouse port of the BX and IX microscopes it may be necessary to purchase a separate adapter which is available from Olympus.
