Multiple configuration options are available using the DC4100 or DC4104 LED Drivers.
Our 4-wavelength LED sources may be used directly with either the DC4100 or the DC4104, while our fiber-coupled, collimated, and heatsink-mounted LEDs require the use of a DC4100-HUB. Metal-core PCB LEDs are also compatible through the use of a DC4100-HUB and CAB-LEDD1 cables as pictured above.
Features
- Four Channels with Individual Current Adjustment
- Choose from Models with One (DC4100) or Four (DC4104) Separate Modulation Inputs
- Fast Switching Times of 1 ms Resolution Using the Modulation Input
- Linear Current Source Provides a Reliable and Reproducible Signal
- USB 2.0 Interface for Remote Control
- Compatible with µManager Automation Suite
- Customized Wavelength and Modulation Solutions Available
Thorlabs' DC4100 and DC4014 four-channel LED controllers are designed for microscopy and other applications that require multiple color channels. They are the ideal driver for the LED4D series four-wavelength LED sources. Via the optional DC4100-HUB, they can concurrently drive four high-power LEDs like our collimated or uncollimated mounted LEDs (see diagram to the right). Using the DC4100-HUB connector hub and four CAB-LEDD1 connection cables, these drivers can also be used with four of our high-power LEDs on metal-core PCB or with four user-supplied LEDs. The LED current of each channel can be adjusted independently from 0 to 1000 mA or modulated via an external voltage; for details, see the Operating Modes section below.
These controllers offer a compact housing with a backlit, easy-to-read LCD display. They are operated via a wheel selector and three buttons on the front panel. Additionally, both LED drivers can be remotely operated via USB 2.0 by the included software package with an intuitive GUI and an extensive driver set. The LED drivers are also compatible with µManager, a versatile, open source, GUI software platform for automated microscopy. A plugin allows the user to control the LED drivers right out of the box.
Operating Modes
- Constant Current Mode: Each LED current is set to a separate, constant milliamp value. This mode is ideal for general-purpose applications.
- Brightness Mode: Each LED current is set to a separate value as a percentage of the maximum current. This mode is ideal for applications involving fluorescence microscopy.
- External Control Mode: The LED current is modulated through an external trigger. For the DC4100 controller, all activated LEDs are controlled by the same modulation signal but can be individually deactivated. For the DC4104 controller, each LED is controlled by a separate modulation signal, all of which are provided through a single, included cable. Both controllers accept voltages ranging from 0 to 10 V, with 1 V corresponding to an LED current of 100 mA.

(posted 2020-08-03 11:24:24.44) To whom it may concern,
Is there anyway I can get a more detailed document that describes the TLDC4100_32.dll? I need to be able to control some LEDs from a custom application but the current DC4100 Manual does not give enough information to write the code for such an interface. Thank you.
Best Regards,

(posted 2020-03-17 16:59:07.053) This question is for the DC2100, but if the DC4100 has the same spec then all the better:
What is the delay time from an external trigger to the LED drive output? At both turn-on and turn-off when running in External mode.
I'm doing some time critical measurements synchronized to a CMOS imager and need to know this parameter. The spec only give the Rise/fall time - which is slightly different. nreusch
(posted 2020-03-26 03:32:27.0) This is a response from Nicola at Thorlabs. Thank you very much for your feedback. The delay of an LED with respect to the external trigger input depends on several factors: The capacity of the LED itself, cord capacities as well as drive current and modulation frequency. While we cannot specify a specific value for neither DC2100 nor DC4100, I will contact you directly to send you some exemplary measurements. Khoa Nguyen
(posted 2020-02-17 14:09:53.887) Can you make more than 4 channel LEDs, such as a custom number of channels? dpossin
(posted 2020-02-19 06:02:56.0) Dear Customer,
Thank you for your feedback. Unnfortunately we can not increase the number of channels for our DC4100 LED controller but we recently released a 6 wavelength source. You can have a look here: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=13597. Gary Yellen
(posted 2019-07-10 17:07:34.763) I purchased this item together with my Bergamo laser scanning microscope. I have downloaded the GUI, but would really like to control this in coordination with my TSI Quantalux camera. It doesn't appear there is any native support for the LED controller in ThorimageLS.
Is there an SDK (or at least documentation on the USB command stream) that would allow me to control this device from MATLAB? dpossin
(posted 2019-07-17 09:12:34.0) Dear Gary,
Thank you for your feedback,
It is not possible to controll the DC4104 from the Thorcam software but the Quantalux as well as the DC4104 can be triggered externally. You can feed a TTL signal from an external source into the camera and the LED driver in order to synchronize them.
The SDK files and the corresponding API you can find in the corresponding folder "Scientific Camera Interfaces". a woehl
(posted 2019-07-02 12:23:58.37) Hi, We are have some troubles getting the DC4104 to work with uManager (Win10). We have installed the most recent version of the control software (v2.2), yet when we run the hardware configuration wizard in uManager we see ThorlabsDCxxxx (unavailable). Any ideas? Perhaps we need a previous driver version for the uManager device adapter? Many thanks for your help!!! MKiess
(posted 2019-07-04 10:45:17.0) This is a response from Michael at Thorlabs. Thank you very much for your inquiry! The DC4104 is compatible with Windows 10 and MicroManager. If the DC4104 LED drivers are installed correctly and are shown in the Windows device Manager, you can install the DC-LED-drivers in MicroManager. I will contact you directly for further assistance. tou-cheu.xiong
(posted 2017-12-01 19:20:11.23) Hi
we have purchased the controller DC4104 and we would like to plug a LED strip. Unfortunate the controlleur could not identify any LED. Could you please let me know if it is possible to connect a LED strip (only anode and cathode) to this controller?
Thank you swick
(posted 2017-12-05 03:50:54.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry. Compatibility to DC4104 depends on properties of the LED like forward voltage and electrical current. I have contacted you directly for assistance. user
(posted 2017-10-26 15:36:36.797) Hi,
Is there a way to program directly the DC4104? I couldn't find any API for thhis controller.
Of course there is the option to control the LEDs via the external trigger but I would like to be able to also change/select the channels (LEDs) that are under the external control. That's also because every time the device is switched off and on I have to manually re-select the active LED.
Thanks,
Daniel wskopalik
(posted 2017-10-27 07:28:31.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry.
The DC4100 and DC4104 can be controlled using the driver files available in the tab "Software" of this website. These files include a documentation of the driver commands as well as some example codes.
Unfortunately, you didn't leave an email address but please feel free to contact me any time at europe@thorlabs.com. simon.walker
(posted 2017-08-11 17:54:37.943) I would like to use the DC4100 with some high speed cameras. The cameras will be running at about 4Khz, with 10% duty cycle (i.e. an exposure time of 25us). They produce a 5V ttl pulse output, which is high during the exposure and low (0V) at other times. Can this be used to sync the DC4100 so that the LEDs turn on during the exposure and are off at other times?
Thanks,
Simon nreusch
(posted 2017-08-17 06:13:12.0) This is a response from Nicola at Thorlabs. Thank you very much for your inquiry. The DC4100 is suitable for an external trigger input up to 10 V and a modulation frequency range of 0 to 100 kHz for sine wave modulation. So you could use a 5 V TTL pulse with 4 kHz repetition rate. Please note that 1 V of the trigger input signal will correspond to 100 mA, so 5 V equal 500 mA. In order to decide whether the DC4100 would really meet your requirements, I will also contact you directly to discuss your application in more detail. kkomar
(posted 2017-05-29 14:57:21.033) I'm planning to use DC4100 with one of the diodes: MNWHL4 or MWWHL4 to switch on one them for relatively short time (50 us to 500 us) but with extremely low frequency (0.2 to 0.01 Hz). If the modulation signal of such low duty cycle will be connected with the trigger input of the DC4100 what would be main limiting factor: LED or the driver? Where can I check the rising time of Thorlabs LEDs? swick
(posted 2017-06-01 03:42:42.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry.
The bandwidth of DC4100 is 0 - 100 kHz, small-signal, sine wave.
If modulating with a waveform other than sine wave, the functional bandwidth will be reduced. I will contact you directly to discuss your application in detail. l.volkers
(posted 2017-01-31 04:41:09.943) I've read the software manual and it's not clear to me, whether there is a possibility to use the DC4104 as a pacing device. And if so, which additional devices/cables/software would be best functioning in combination with this device?
Best regards,
Linda wskopalik
(posted 2017-02-01 03:55:05.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry.
The DC4104 can be externally modulated up to 100 kHz with a sine wave signal. The current applied to the connected LEDs will be modulated corresponding to the applied signal.
I will contact you directly to discuss your requirements and to provide further assistance. sergio.sigala

(posted 2016-06-23 02:40:05.613) There are few systems in production using DC4100, we are facing intermittence LED light off in one of the channel (i.e always channel 1).
We have swapped the DC4100, but the problem still remain the same.
For recovery, we have to power cycle the DC4100.
Does your site have any advice for this issue ? What could have caused this LED light off.

I would like to know the time resolution in the External Control Mode. And could we apply "sine waves" or any waves in the External Control Mode?
Thank you.
SunJ jvigroux
(posted 2013-09-27 08:03:00.0) A response from Julien at Thorlabs: The time resolution of the analog circuit used for the external voltage control is extremely low but the limiting factor for fast application is normally the rise time of the output stage driving the LEDs. This time is usually in the low µs range (the exact value varies from LED to LED). Any type of modulation (sine, square, triangle etc.) can be applied to this input provided of course that the driving signal is not faster than the above mentioned rise time. jlow
