ZNPX14 is a Plano-Convex Infrared Lens, made of ZnSe material. It has a diameter of 25.4 mm, and an effective focal length of 150 mm. Zinc Selenide is an excellent material choice for IR lens because it can cover a large wavelength range, from 600 nm to 16 µ. 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.
