Only OEM pulsed laser driver (CW/QCW) offers convenient integration due to its small size (smallest in the market), low amount of generated heat and flexible control interface capabilities. Integrated driver can be controlled by accessing front side control buttons and LCD screen or by connecting the USB interface to a computer or tablet.
Only OEM is ideal for medical direct laser diode applications. It powers single-emitter diode lasers featuring up to 25 W of optical output power, runs aiming (pilot) beam laser diode and controls cooling fan or water pump to ensure temperature stabilization.
Features:
- QCW and CW operation modes
- Plug-and-play configuration
- Integrated quartz based pulse generator
- Fan/water pump controller
- Standard mini USB 2.0 interface for remote control
- Low current aiming beam driver
- Interlock channel on D-SUB37 for connection of key e. stop or power on switch
- Gate function for pulse trains generation or control of laser diode from external pulse generator
- Two NTC inputs; the second input can be programmed to support external control pedal (for medical applications)
- Two lines text LCD screen
- 1 year full service warranty
Design:
- All solid capacitors
- No wired connectors
- No hand soldering
