Dichroic Splitters are thin film filter components for splitting a light beam into a transmitted and a reflected beam with separate spectral wavelength ranges. Used in the reverse direction, Dichroic Combiners converge two separate light beams into one beam while filtering a specific wavelength range from each incoming beam.
Dichroic Splitters/Combiners meet very narrow spectral band edge tolerances and ensure maximum spectral stability and very low residual optical absorption loss. The dichroic filters/mirrors are produced by an advanced sputtering deposition process, providing very dense filter coatings with excellent optical and mechanical stability, both at elevated operating temperatures and under varying environmental conditions. Dichroic Splitter/Combiner components are manufactured on various standard sheet glass types in different shapes and sizes, or can optionally be coated on other substrates upon request.
