Select Wavelength Laser Diodes for Gas Detection:SWLD

Description:

The SWLD series laser is specifically developed fbr Gas Sensing systems. It is available in a hermetic sealed 14-pin butterfly package. The laser diodes contain thermoelectric cooler (TEC), thermistor, monitor PD and optical isolator to secure high quality laser performance. We also have full customer selection of output powers, package types and output fibers of SM fibers, PM fibers and other special fibers. Our laser products are Telcordia GR-468 qualified, and in compliance with RoHS directives.

Applications
