600-1100nmPolarization Extinction Ratio Meter

The Polarization Extinction Ratio Meter is a high-precision optical testing instrument used to measure the polarization extinction ratio (PER) of polarization-maintaining devices and the polarization characteristics of light sources. The instrument adopts advanced polarization analysis and data processing technology to achieve fast and stable measurement of parameters such as polarization extinction ratio and polarization angle, and intuitively displays the test results. The product features a wide measurement range, high accuracy, good repeatability, and fast test speed. It supports a wavelength range of 600–1100 nm and PER measurement up to 30 dB. It is also equipped with an RS232 communication interface, enabling remote control and data acquisition through a host computer. It is suitable for the R&D, production, quality inspection, and scientific research experiments of polarization-maintaining fibers, fiber-optic devices, and other polarization-related optical devices.
