Shortpass Filter

The passband filter is a kind of filter, which can separate a certain wavelength band of monochromatic light.

A filter that separates a certain band of monochromatic light from the composite light. It has a symmetrically distributed light transmittance curve, and the light transmittance is the largest at the center wavelength. At half of the peak transmittance, the wavelength spacing Δλ between two symmetric points on the transmittance curve is the bandpass half-width of the filter. Divided into narrowband filters and broadband filters. Used for spectroscopy instruments to eliminate the overlap of grating spectral levels.

The narrow-band filter is subdivided from the band-pass filter, and its definition is the same as that of the band-pass filter, that is, the filter allows the optical signal to pass through in a specific wavelength band, and deviates from the band outside this band. The optical signals on both sides are blocked, and the passband of the narrow-band filter is relatively narrow, generally less than 5% of the central wavelength value. Its main parameters are: center wavelength, half-width (bandwidth), peak transmittance, cut-off range, cut-off depth (OD value).
