    The PL-DFB-795-A-A81 795nm DFB laser diode module made by LD-PD is a cost effective, highly coherent laser source. The DFB laser diode chip is packaged in an industry standard hermetically sealed 14 pin butterfly package with TEC and PD Built in.We special design the area only work in room Temperature. Our diode has good performance from 20-30℃.
