Newport’s IR Plano Convex lenses made up of Calcium fluoride, Zinc Selenide, Sapphire and AMTIR are ideal for IR applications (180 nm-16000 nm). Calcium fluoride (CaF₂) lenses can be used for applications requiring high transmission and minimum chromatic aberration between deep UV to Mid IR wavelengths (180 nm-8000 nm). AR coated Zinc Selenide (ZnSe) lenses are good for many applications using near IR to mid IR lights (800 nm -16 µm), and for experiments/instruments using CO₂ lasers. Sapphire lenses are particularly good for high pressure and vacuum applications. Zinc Selenide and Calcium fluoride lenses are also good to use with femtosecond IR pulses due to its relatively low group velocity dispersion (GVD) in IR wavelength regime.
