ZNPX18 is a Plano-Convex Infrared Lens, made of ZnSe material. It has a diameter of 25.4 mm, and an effective focal length of 1000 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.


ZNPX18是一种由ZnSe材料制成的平凸红外透镜。它的直径为25.4 mm,有效焦距为1000 mm。硒化锌红外透镜材料是一个很好的选择,因为它可以覆盖很大波长范围,从600纳米到16µm。它的低吸收系数使其成为使用二氧化碳激光器的理想应用/仪器。在中红外环境下,该材料表现出非常低的GVD,这使得它适合于飞秒红外脉冲的应用。
