Products Description
Filters with cut-off zones on both sides of the transmission band of the spectral characteristic curve are called bandpass
filters. Bandpass filter is an important optical thin film component, which has been widely used in chemistry, spectroscopy,
laser, astrophysics, optical fiber communication, biology and other fields. The spectral curve of the bandpass filter prepared by the principle of light wave interference, the wavelength near the spectral transmission region is called the pass band of the filter, usually both sides are the cut-off zone, and there may be a bypass band around the cut-off area, usually need to use colored glass, absorbing film or cut-off filter to eliminate the bypass band
