High-quality short-wave pass filter has the advantages of wide cut-off bandwidth, deep cut-off depth, high conversion steepness, and high transmittance. It can be widely used in fluorescence excitation spectrum measurement, Raman spectroscopy applications, spectral grouping applications, and astronomical observation applications, etc. It can also be widely used in imaging optical systems and machine vision system applications to eliminate interference light outside the available band. Improve imaging clarity and system sensitivity.
