Wavelength Combinations
Each LED4D source contains four individual high-power bare LEDs. Use the configurator below to build your LED4D 4-wavelength source by choosing from the 14 available LEDs listed in the table to the right. Due to the optical configuration, certain wavelengths cannot be combined within the same source. As you select each wavelength in the configurator, unavailable wavelength pairs will be excluded from each consecutive drop down menu.
Additional limitations imposed by the full configuration are outlined in the table to the right. Each combination of two wavelengths that cannot be included in the same 4-wavelength source is marked in grey, while available combinations are indicated by a green- or orange-shaded cell. The latter denotes a wavelength pair where the selection of the final two LEDs is further limited: LEDs with wavelengths below 455 nm cannot be included in an LED4D source with 660 nm, 617 nm, and 590 nm or 565 nm as the other three wavelengths. The configurator below is designed so that you cannot order a source with an unavailable wavelength configuration.

- Switching and Intensity Adjustments via Individual LED Current Settings
- Better Stability and Longer Life than Gas Discharge and Halogen Lamps
- No Moving Parts for Vibration-Free Operation
- Cooling Fins Provide Efficient Thermal Management
- Long Lifetime Light Source (See the LED Specs Tab for Details)
- Optional Adapters for Olympus, Nikon, Zeiss, and Leica Microscope Lightports
- Optional Adapter for Coupling to Liquid Light Guides (LLGs)
The LED4D 4-Wavelength High-Power LED Source is ideal for applications requiring up to four wavelengths of light. This user-configurable light source efficiently combines the output of up to four LEDs into a single collimated beam. Together with a DC4100 or DC4104
Compared to conventional non-LED sources such as halogen and gas discharge lamps, these 4-wavelength sources offer many advantages such as higher signal-to-noise ratios (due to narrow bandwidth emission), better stability, longer life, lower replacement costs, simple operation without maintenance cycles, and no active cooling requirements or thermal filtering due to minimal thermal loads. The LED current can be adjusted to quickly set the intensity via the DC4100 or DC4104 driver (sold separately) front panel or USB connection, making this source an ideal choice for microscopy applications where multiple wavelengths are required. For the DC4100, the amplitude of each of the four LEDs is independently adjustable but the modulation (via external signal) is the same value for all. Both the modulation frequency and amplitude are individually controllable for all four LEDs when using the DC4104 model driver which accommodates four external signal inputs (see the full web presentation of these drivers for details).
The LEDs incorporated into these sources are characterized by high divergence. The light is guided through the system using mirrors, and the output is collimated with an aspheric condenser lens. This setup inherently leads to a reduction in the measured output power (as seen in the table to the right) compared to that of the bare LEDs. Thorlabs also offers single-channel collimated LEDs, which have higher power outputs since wavelength-combining optics are not needed.
Adapters
Optional adapters are available for using the 4-wavelength LED source with liquid light guides or microscopes. The output aperture of these LED sources is internally SM2 (2.035"-40) threaded. For Olympus, Nikon, Zeiss, and Leica microscopes, SM2-threaded adapters are available that directly mount the 4-wavelength sources onto the microscope lightport (see SM2-Threaded Microscope Adapters). See below for a video that demonstrates how to install the source on an Olympus microscope.
Alternatively, the LED4B1 Adapter for Liquid Light Guides (LLGs) is used to couple light exiting the LED source into a LLG. It replaces the SM2-threaded output port with an aperture that is internally SM1 (1.035"-40) threaded. The adapter contains an optic designed to focus light into the aperture of a LLG held by the appropriate LLG-to-SM1 adapter (AD3LLG for Ø3 mm core LLGs or AD5LLG for Ø5 mm core LLGs). More information on these adapters and Thorlabs' selection of liquid light guides can be found here.

Thorlabs' 4-Wavelength LED Source can be made compatible with our Liquid Light Guides (LLGs) with the addition of the LED4B1 adapter. The animation to the right and the text below detail the installation process.
Remove the SM2-threaded (2.035"-40) output port that comes installed on the 4-wavelength source by unscrewing the four M2.5 screws. Position the LED4B1 over the output of the 4-wavelength source so that the M2.5 counterbores line up with the tapped holes on the LED source housing. Use the M2.5 screws that came with the LED source to fasten the adapter in place.
Screw an SM1-to-LLG adapter (either the AD3LLG or AD5LLG, not included) into the SM1-threaded (1.035"-40) exit port of the LED4D1, and plug your LLG into the adapter. Tighten the setscrew on the side of the SM1-to-LLG adapter using a 0.05" hex key to secure the LLG in place.

(posted 2024-09-18 13:23:37.707) Good Afternoon
Would it be possible to couple a fibre-optic to the output of the LED source unit instead of a liquid light guide? What would be the downside of doing so? Could you possibly recommend a fibre?
Many Thanks hchow
(posted 2024-09-19 03:40:47.0) Dear Mr. Curnock, thank you for your Feedback. It is indeed possible to couple light from the 4-Wavelength High-Powere LED source into a regular multimode fiber. The problem is the amount of light throughput into the fiber. Given that the aperture of the LED4B1 is still rather quite large, the amount of light getting collimated onto the small core of the multimode fiber would be next to negligible. If you want, you could potentially lengthen the LED4B1 with an additional lens tube and place a secondary aspheric lens in order to collimate the light down to a smaller point. There will inevitably be quite a bit of loss of light, so choosing a multimode fiber with a larger core diameter would be ideal. Otherwise, you could always purchase 4 separate fiber coupled LEDs and use the BF46LS01, 1-to-4 Fan-Out Fiber Bundles, to collimate the light into one singular fiber. Stephen Thornquist
(posted 2024-04-30 15:40:41.743) I'm looking for an extension cable to the 4-channel high power LED source connecting to a DC4104. The cable that came with our source is frustratingly short and it makes it difficult to use. But I can't find an option online -- is there anything you can provide? hchow

(posted 2020-11-12 20:58:57.98) Hi, can we use one wavelength at a time?? Or, all channel (4 wavelength) will be activated during operation. wskopalik
(posted 2020-11-13 04:03:43.0) Dear Atanu,
Thank you very much for your inquiry!
Yes, you can also just use one wavelength at a time. Each LED can be individually controlled on the LED drivers. There is just one limitation on the DC4100 driver. All activated LEDs are controlled by the same modulation signal on this driver but can be individually deactivated. For the DC4104 controller however, each LED is controlled by a separate modulation signal, all of which are provided through a single, included cable. So if you want to control each LED individually by external modulation the DC4104 would be the best solution.
I will contact you directly to provide further assistance. user
(posted 2020-06-11 11:42:07.233) Hi! I am really interested in buying the 4-LED module with wavelength 470 nm, 530 nm, 590 nm, and 625 nm. For my application, the spectral bandwidth needs to be smaller than 10 nm so I wonder in front of each LED we can insert a bandpass filter. This filter will be before the dichroic mirror so it only affects each individual LED. I am completely aware that the intensity will be reduced. I would prefer to order it with this modification. However, I am happy to do this change by myself. Any feedback? dpossin

(posted 2018-10-31 09:33:15.147) Dear ThorLabs,
with respect to your LED4D067 = 4-wavelength high power LED source (aka "4LED"), can:
* LEDs be moved by me between two 4LED sources?
** if no, can I custom specify what LEDs go in each of two units ... and work with you to specify beam combiners?
* do you offer a "merge module" to combine outputs of two 4LED sources (before going to LLG or back of microscope)?
thanks,
George nreusch
(posted 2018-11-09 10:08:24.0) This is a response from Nicola at Thorlabs. Dear George, thank you for your inquiry! We can offer to change the LED configuration of the 4-wavelength LED source as service, but we strongly recommend sending the source to us, as we need to readjust the LED source. Unfortunately, we do not offer a universal merge module, but you might be able to use a beam combiner for this purpose. Please contact your local Tech Support team for further information. xuy

(posted 2016-10-03 11:45:08.86) Could you please provide information about the RGB mixing ratios / drive currents in order to achieve white light output from this LED source? Thanks swick
(posted 2016-10-04 04:02:42.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry.
Unfortunately, the four wavelength LED source is not designed to emit white-light based on superimposing four LEDs.
The spatial profile of intensity is non-constant, which makes it impossible to achieve proper white-light over the full clear aperture.
I will contact you directly to discuss alternatives. thobra

(posted 2012-12-19 09:50:00.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. Unfortunately we do not have a setup yet were it is possible to couple light from a 4-color LED source into a liquid light guide. However, you could use a lens tube, for example SM2L30, with an aspheric condenser lens, for example ACL5040-A. The lens tube fits into the SM2 threading on the 4-color LED source. To mount a liquid light guide you can use two adapters, SM2A6 and AD5LLG. It is a good idea to have a complete setup with an aligned lens. I will forward this idea to our development department so that we will be able to offer a part like this in the future. Best Regards, Thomas heyderc

(posted 2012-11-14 06:29:00.0) A response from Thomas at Thorlabs: Thank you for your inquiry! The lower power is caused through losses inside the housing. The divergence of the LED-Chips is very high and the beam is guided with mirrors to the condenser lens for collimation. Because of this setup a lot of optical energy gets lost. The lens of a single collimated LED is located directly in front of the LED-Chip and this causes almost no losses. eozkan

Thanks jvigroux
(posted 2011-12-19 13:09:00.0) a response form Julien at Thorlabs: Thank you for your feedback! the design of the LED4C LED source only allows the simultaneous use of four different wavelengths. Further, there is to our knowledge no high power LED available at 340nm. We should discuss more closely what the exact requirements for your application are as based on the exact output power required, there might be some other type of setup allowing to achieve the wavelength combination you need. Unfortunately, for now the use of the software within MetaMorph/MetaFluor is not yet implemented. The suggestion to emulate the Sutter filter wheel seems like a goop approach. Our software engineers are having a look into this and I should be able to post further information about the feasibility of such approach within the next 2-3 weeks. gmcnamara
(posted 2011-12-16 19:03:14.0) I would like to use a 4LED - or better yet 5LED - for Fura-2 Calcium ion ratio imaging, plus GFP, DsRed and Cy5/Alexa Fluor 647 (not necessarily at one time). I will need:
~340 nm LED (in addition to 385, 470, 530 and hopefully 627 LEDs).
specific bandpass filtes to eliminate the tails of the LED spectra - especially so that I can have a clean separation of ~340 nm from ~385 nm light.
I can select the appropriate filter sets for inside my microscope, once you/I/we figure out the LED bandpass filters. Probably a Fura-2 + Cy5 filter set and a DAPI/Green/Red triple pass set.
I find your 4LED + microscope adapter product selection line-up on your web site confusing.
I need more useful software integration than uManager. You never posted a follow-up to the 2009-11-24 posting about third party software. I am especially interested in MetaMorph/MetaFluor. If you do not want to work with vendors one by one, a suggstion: consider emulating a Sutter 10-2 filter wheel and shutter, with USB control (you can use the uManager Sutter interface to test the emulation). bdada

(posted 2011-11-07 18:25:14.0) Interested in using it for a different application, but I'm having difficulty determining the output levels. May need different output optics. Can they be changed? Contact me and I'll explain the application. jvigroux
(posted 2011-08-10 11:48:00.0) A response from Julien at Thorlabs: Thank you for your feedback. As of now, we do not have dichroic mirrors that allow to cover the necessary spectrum for the combination you need (from 450nm to 850nm). This is the main reason why the maximum wavelengths for those four colors LEDs is about 670nm. Maybe an different arrangement using single LEDs could also work for your application. I will contact you directly to discuss this approach. pbenzel

(posted 2010-12-07 07:06:28.0) I purchased LED4C and olympus adapter but I cannot find the right way to mount this LED4C with the olympus adapter LED4A1.
my microscope is olympus IX71.
Please let me know how to mount
Thank you.

(posted 2009-11-20 08:48:06.0) Hi again,
Forgot to ask if this system will work with Metamorph, Slidebook or Olympus SIS software or other software.
Please advise.

The LED4B1 Adapter for Liquid Light Guides contains an aspheric lens (Item # ACL2520-A) to focus light from the 4-wavelength LED source into a liquid light guide (LLG). The adapter is SM1-threaded and requires a separate SM1-to-LLG adapter (sold separately). We offer the AD3LLG SM1 Adapter for Ø3 mm Core LLGs and the AD5LLG SM1 Adapter for Ø5 mm Core LLGs. Thorlabs' selection of liquid light guides can be found here.
The table to the right shows the output power of the 4-channel LED with the LED4B1 adapter. The adapter, which contains only one lens, replaces the two lenses and ground glass diffuser included in the 4-channel LED head. Thus, The LLG adapter provides less attenuation compared to the free-space output of the 4-wavelength LED source alone. Therefore, the output powers provided in the table to the right will differ from those specified with the standard 4-channel LED head.
The LED4B1 has the same bolt pattern as the the 4-wavelength source's SM2-threaded collimating output port. To install, simply remove the SM2-threaded output port by unscrewing the four M2.5 screws and attach the LED4B1 adapter in its place using the same four screws. Then thread in the LLG adapter and install the LLG. Detailed installation instructions may be found on the LLG Installation tab above.
