Product description

The long-wave pass filter allows light whose wavelength is greater than the set wavelength to pass, and cuts off the light whose wavelength is less than the set wavelength. It has the advantages of wide cut-off bandwidth, deep cut-off depth, high conversion steepness, and high transmittance. Widely used in fluorescence excitation spectroscopy, Raman spectroscopy applications, spectral grouping applications, and astronomical observation applications, etc. It can also be used in imaging optical systems, machine vision system applications, to eliminate interference light outside the available bands, and greatly improve imaging clarity Degree, and the sensitivity of the system.
