Applications

  • Driver for Four Wavelength LED Source: LED4C Series
  • Fluorescence Microscopy with Multi-wavelength Requirements

This new four-channel LED controller series is designed to drive up to four high-power 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 3 Operating Modes section below. These controllers are designed for microscopy and other applications that require multiple color channels. They are the ideal driver for the LED4C Series 4 Color LED Source. Via the optional DC4100-HUB, they can drive four high brightness LEDs like our mounted LEDs (collimated / uncollimated) at the same time.

The DC4100 and DC4104 controllers offer a compact housing with a backlit, easy to read LCD display. They are operated via an intuitive GUI, a wheel selector plus three buttons on the frontpanel. 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 GUI software, µManager, is a versatile, open source, software platform for automated microscopy. A plugin allows the user to control the LED drivers right out of the box.

3 Operating Modes

  1. Constant Current Mode: The LED current is kept constant to a preset milliamp value. This mode is ideal for general-purpose applications.
  2. Brightness Mode: Controls the LED current but is set as a percentage of the maximum current. This is optimal for general and fluorescence microscopy applications. The LED current in the Constant Current and Brightness modes can be individually set for each LED.
  3. External Control Mode: Allows the user to control the LED current for all connected LEDs by a single external modulation input for all channels (DC4100) or 4 independent external modulation inputs for each channel (DC4104) with a voltage of 0 to 10 V. Here 1 V corresponds to an LED current of 100 mA. The External Control Mode can be used to modulate the LED current over time. For the DC4100 controller, all activated LEDs are controlled simultaneously, but individual LEDs can be deactivated. For the DC4104 controller, a separate modulation input can be applied to each LED via a single cable (included).

Optional DC4100-HUB

The optional DC4100-HUB allows to connect four individual high brightness LEDs, like Thorlabs Mounted LEDs (collimated / uncollimated), to the DC4100. Each LED is connected by a standard M8x1 sensor circular connector. The DC4100-HUB has to be ordered separately.

Hello, I have a question about DC4104 driver. Can I modulate the brightness of each of 4 LED externally using this driver? Do you provide necessary cables?

Dear customer service, I was using the dc4100 (which is great) succesfully controlling it from labview untill some days ago. Then we swapped to a 64 version of labview and the libraries are not considered valid anymore, is there a 64bit version of the drivers. Best regards, Niccolo
