High Performance Shortpass Filter

Shortpass filters provided by YZSY Optics feature wide blocking bandwidth, high blocking depth,high transmission and high blocking slope. Widely used in fluorescence excitation spectrum measurement, Raman spectrum, spectral group, astronomical observation application etc., they are also be widely used in imaging optical systems and machine vision systems to eliminate interfering light whilst improving the imaging quality and sensitivity of the system.
