Narrow Band Pass Interference Filter

Narrow band interference filter, as one of the band-pass filters, is wavelength-selective by virtue of the interference effect of electrolyte and metallic multi-layer coating. Meanwhile, its half bandwidth (HBW) ranges from 1mm to 40mm.
As an alternative to expansive optical spectrometers (such as optical grating), narrow-band interference filter could be widely used in optics experiment and industrial field.
