Package with a built-in lens improves ease-of-use
The lens integrated package for DFB-CW type QCL is sealed and collimated
housing. The internal lens provides collimated output beam radiation. TEC
(peltier) and thermistor for temperature stabilization of QCL-laser chip are
inside the housing. The built-in lens makes the QCL easy to use, eliminating
the need for beam alignment.
Difference from conventional product
Contains a collimation lens with no change in package size.
Needs no additional collimation lens (A11331 sold separately).
