Low-loss Dichroic Beamsplitters

Optics Balzers dichroic beamsplitters separate the incoming light in a highly reflected and transmitted part. The transition zone can be reduced to approx. 3 % of the transition wavelength for random polarized light. The all-dielectric interference filters are deposited by plasma-assisted processes and show extreme environmental stability. Filter dimension and spectral performance can be customized. Short-pass and long-pass beamsplitters are available.
