Polarization Maintaining Bandpass Filter
The PM Bandpass Filter is a micro optics device based on environmentally stable thin-film filter technology. It is used to block out unwanted wavelength bands in fiber laser systems. The components are characterized with high isolation, low insertion loss, high extinction ratio, excellent environmental stability and high power handling capability.
