CW quantum cascade laser

L12004-2190H-E

The lens integrated package for DFB-CW type QCL is sealed and collimated housing. Internal lens provides collimated output beam radiation. TEC (peltier) and thermistor for temperature stabilization of QCL-laser chip are inside the housing. The lens integrated package allows to use under good usability without beam alignment of invisible mid-infrared laser.
