Zinc Selenide Infrared Optics

Zinc selenide (ZnSe) is a popular material for infrared optics due to its excellent transmission in the infrared wavelength range (0.6 to 20 μm). It is a chemically stable material with low absorption and scattering losses, making it suitable for high-power laser applications. ZnSe optics are commonly used in a variety of infrared systems, including thermal imaging cameras, laser systems, and medical devices. Its high refractive index allows for efficient focusing and collimation of infrared light. One of the key advantages of ZnSe optics is their wide transparency range, which extends beyond the visible spectrum. This makes it possible to use ZnSe lenses and windows for both visible and infrared imaging applications. ZnSe optics can be manufactured in various forms, including lenses, windows, prisms, and mirrors. They can also be coated with anti-reflection coatings to further enhance their transmission properties. However, it is worth noting that ZnSe is a relatively soft mate…
