Thorlabs' new DC2100 LED Driver is designed for the operation of very high power LEDs or high power LED arrays. This compact LED source provides a high current up to 2 A and high forward voltage up to 24 V. The pulse width modulation mode allows control of single pulse of a connected LED. The user can adjust: current, pulse frequency, duty cycle, and number of pulses. The user also has the option of using an external trigger to control the LED current. The external trigger voltage frequency can be modulated up to 100 kHz. This LED driver can be remotely operated via USB2.0 by the included software package with an intuitive GUI and an extensive driver set.

The DC2100 belongs to Thorlabs line of ultra-stable, high-brightness LED drivers for demanding scientific applications that are sensitive to even small high frequency brightness fluctuations. Typical applications range from the operation of very high power LEDs and LED characterization to microscopy applications that need to control individual LED pulses.

If connected to the Thorlabs MxxxL1 Series Mounted LEDs that are equipped with an EEPROM, the DC2100 automatically reads the stored LED data and adjusts its settings, e.g. the maximum current is read and used to avoid damage of the connected LEDs.

This driver is compatible with µManager, a versatile open source software platform for automated microscopy. A plugin of the µManager allows to control the LED driver from this software out of the box.

 

Operation Modes

1. Constant Current
   For Visual Inspection, Adjustable LED Current: 0 to 2 A in 1 mA steps.
2. Pulse Width Modulation Mode
   Control mode for single LED pulses with adjustable LED current (0 - 2 A),
   pulse frequency (1 Hz - 10 kHz), duty cycle (1 - 100%), and number of pulses
   (1 - 100 or continuous pulse emission)
3. External Control Mode
   Customizable External Trigger Mode with adjustable modulation frequency
   up to 100 kHz, Input Voltage 0 to 10 V (1 V corresponds to 200 mA LED Current )
