The latest laser diode drivers LDD-1124, LDD-1121 and LDD-1125 are members of the digital LDD-Family and feature a microcontroller and a FPGA.

Our LDDs are ideally complemented with our TEC-Family precision Peltier temperature controllers.

 

Pre-assembled cable on plug for laser diode object temperature and laser power measurements. Compatible with LDD-1124, LDD-1121 and LDD-1125 laser diode drivers.

1U rack enclosure with HMI, intelligent cooling and modular power supply for turn-key integration and stand-alone operation of up to four internal OEM laser diode drivers or/and TEC controllers. The LTR-1200 case transforms your devices into rack-mount or table-top instruments.
