Description

DL-series is a family of fiber-coupled diode lasers. Each laser consists of a fiber-coupled diode module, current source (laser diode driver), cooling system (Peltier modules, temperature controller, heatsink and fans), user interface and coverage case.

We use only high quality fiber-coupled diode modules from the world-best manufacturers. Standard models are built up on nLight's modules. Modules by other manufacturers like Dilas, LIMO, JenOptics can be used instead on customer's request.

Laser's input is 110/230VAC mains, laser's output is a fiber, which distal end can be equipped with beam shaping optics of customer's choice. Interfaces are 7'' touch panel GUI and RS-485 machine interface.
