PM Bandpass Filter

The 1030nm,1064nm,1550nm Optical Bandpass Filter is based on thin-film filter technology that passes wavelengths within a certain range and rejects (attenuates) wavelengths outside that range. The Optical Fiber Band Pass Filters features high isolation, low insertion loss, PM fiber type and high power handling available upon request.

Specification

PM Fiber Bandpass Filters

Polarization Maintaining Fiber-Based Components

These Polarization Maintaining Band Pass filters (PM Fiber Bandpass filters) is base on thin-film filter technology which offer high power handling and excellent environmental performance. GEZHI can offer 1030nm , 1064nm, 1050nm or customized wavelength PM band pass filter.
