Near-IR DFB Laser in TO39 Package for TDLAS - Near-IR

Product Specification

Near-IR DFB Lasers

NORCADA designs and manufactures single mode semiconductor distributed feedback (DFB) lasers for industrial sensing and environmental monitoring applications. Our DFB lasers come with two main styles of hermetic packaging configurations designed for excellent temperature stability and wavelength tuning.

Near-IR DFB Lasers Product Features
