Product Description

Product Description

The narrowband filter is separated from the bandpass filter. It is a kind of bandpass filter. Its definition is the same as that of the bandpass filter. It allows optical signals to pass through in a specific wavelength band, and the optical signals on both sides that deviate from this band are blocked, but the narrow-band filter is relatively narrow. Generally, it is less than 5% of the central wavelength value. The main function of a narrowband filter is to pass light of a specific wavelength and reflect (or attenuate) optical elements of light of other wavelengths.
