概要（Overview）

Techwin polarization extinction ratio meter PER-M500 is used to detect the polarization extinction ratio (PER) of polarization-maintaining devices, the degree of polarization of light sources, the extinction ratio of polarization-maintaining fibers and other polarization-maintaining devices. It’s a new generation of precision optical measuring instrument developed by Techwin with many years' experience in optical device testing. It can be used to measure the extinction ratio of polarization maintaining fiber, the extinction ratio of polarization maintaining device, the extinction ratio of polarization maintaining connector, the polarization degree of light source and the angle of polarization axis. The upper computer software has powerful functions and is easy to operate.
