High Performance Longpass Filter
Longpass filters provide a wide blocking bandwidth, high blocking depth, high transmission and high blocking slope. They are widely used in fluorescence excitation spectrum measurement, Raman spectrum, spectral group and astronomical observation applications. Widely used in imaging optical systems and machine vision systems to eliminate interfering light, the provide improved the imaging quality and sensitivity of the system.
