Product classification
Plane spectroscope
Plane spectroscope is an optical element which can achieve a specific spectral ratio of transmitted light and reflected light by coating multi-layer interference film on the surface of flat glass. It has the advantages of wide spectral range, low dispersion, good color neutrality, solid film layer, good degree of finish, small absorption, etc.
