Description

Bandpass Filters： A IR Cut Filter that separates a band of monochromatic light from a composite light. It has a symmetrical transmittance curve with the maximum transmittance at the central wavelength. At half of the peak transmittance, the wavelength spacing △λ of two symmetric points on the transmittance curve is the bandpass half-width of the filter. Divided into narrow band filter and broadband filter. Used in spectral instruments to eliminate overlap of grating spectral levels.
