Spectroscopic element

Neutral density spectroscopic film is also known as attenuator, ND mirror. It identically and uniformly reduces light of different wavelengths, effectively reduces light, and does not change the color of the original object. Therefore, it can truly reproduce the original color of the object. It has the advantages of wide band attenuation rate, accurate attenuation, insensitivity to incident angle and polarization state, solid film layer, scratch resistance and strong hydrophobicity.

Features

A plane beam splitter is an optical element that coats a multi-layer interference film on the surface of flat glass to achieve a specific split ratio of transmitted light and reflected light. Wide spectroscopic range, low dispersion, good color neutrality, firm film, good finish, low absorption, etc.
