Changchun Yutai Optics Narrow Bandpass Filters can be for Biomedical and Industrial Applications Our 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 2nm and 20nm, and a blocking depth of OD5 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.
