Product Family Description

CaF₂ for 0.8 – 6μm Range
ZnSe for 2 – 20μm Range

Infrared Plate Beamsplitters are critical components in FTIR spectrometers, Interferometers, and other IR-enabled devices. Both the Calcium Fluoride (CaF₂) design, with an operating wavelength range of 0.8 - 6μm, and the Zinc Selenide (ZnSe) design, with a 2 – 20μm wavelength range, are available in multiple sizes. Infrared Plate Beamsplitters are designed for a 15 – 45° angle of incidence, providing easy integration into any instrument’s geometry.
