    ZnSe is an excellent choice for IR lens with its broad wavelength range (600nm- 16 µm). ZnSe has a high index of refraction which normally requires an anti-reflection coating to achieve high transmission. ZnSe is relatively soft with low scratch resistance thus not recommended for use in harsh environment.
