Neutral Beam Splitters

Neutral beam splitters separate light into reflected and transmitted parts without spectral influence.

Typical division ratio is e.g. R:T = 50:50 at 45° light incidence from 400 to 700 nm. Neutral beam splitters can be manufactured for narrow and wide wavelength ranges with different splitting ratios and with or without polarizing effect as well as cemented and uncemented.
