Coatings

Filter coatings (interference filters) are used to isolate the desired spectral range of the continuous spectrum. Depending on the application filters are divided into block (cut off), narrow-band and band.

Beamsplitting coatings are designed to separate the incident beam into reflected and transmitted ones at a predetermined intensity ratio.
