Plano-Convex Lens, Zinc Selenide, 25.4 mm, 75 mm FL, 600-16000 nm
ZNPX12 is a Plano-Convex Infrared Lens, made of ZnSe material. It has a diameter of 25.4 mm, and an effective focal length of 75 mm. Zinc Selenide is an excellent material choice for IR lens because it can cover a large wavelength range, from 600 nm to 16 µm. Its low absorption coefficient makes it a perfect candidate for applications/instruments using C02 lasers. In mid IR regime, the material exhibits very low GVD, which makes it suitable for applications using femtosecond IR pulses.
