材 料：
A filter. Separation of a band of monochromatic light from the composite light filter. It has a light distribution curve of symmetry, the central wavelength of maximum transmittance. Peak transmittance at half wavelength spacing, delta lambda two symmetric point light curve as the half width of pass band filter. Divided into narrow band filters and broadband filter. The spectral instrument for eliminating grating spectrum overlap.
