Dichroic Beamsplitters

Our dichroic beamsplitters meet very narrow spectral band edge tolerances. They ensure maximum spectral stability and very low residual optical absorption losses. Special steep edge designs enable very narrow spectral transition zones between high reflecting and high transmitting wavelength regions even for randomly polarized light. The all-dielectric interference filters are deposited by plasma-assisted processes and show extreme environmental stability. Filter dimension, spectral performance and angle of incidence can be optimized according to customer requirements.
