Dichroic filters and sets

from Andover

Far more durable than dyed plastic or gel-coated types, dichroic glass filters have a hard dielectric film created by thin layers of metallic oxides. These color separation filters are designed to isolate certain regions of the visible spectrum, reflecting rather than absorbing unwanted frequencies. As a result, they not only produce pure, intense color but also withstand the heat and UV energy from high-energy light sources. Commonly used as light balancing filters in color enlargers and photocopiers, dichroic filters are suitable for any application that requires separating the incident energy into two or more light beams.

Features

Provide sharp separation between transmission and reflection
Spectrally stable at changing temperatures and humidity
Available in custom designs, colors, angles of incidence, substrates, dimensions, and coatings
