Product Description

Hard Coated OD4 Optical 850nm IR bandpass Filter

Narrow Bandpass Filter is a major role in light of a specific wavelengththrough, let the other wavelengths of the light reflection ( or attenuation) of optical components. Half wave width is usually controlled in 20nm or smaller.

Changchun Ruiqi narrow bandpass filters are characterized by high passband transmittance, accurate center wavelength, steep filter edges between pass- and blockband, and broadband blocking range. With typical passband width between 2 nm and 20 nm, and a blocking depth of OD5 or more the filters provide an excellent signal-to-noise ratio. In manifold applications, the filters are used to select the appropriate part of the spectrum either from a light source or in front of a photodetector.
