Zinc Selenide Infrared Aspheric Lens 

Zinc selenide (ZnSe) is a commonly used material for infrared optics due to its excellent transmission properties in the infrared wavelength range. It is transparent from the visible to the mid-infrared region (up to 14 microns) and has a high refractive index, making it suitable for use in infrared aspheric lenses. Aspheric lenses are designed to have a non-spherical surface, which helps to correct for aberrations and improve optical performance. In the case of infrared aspheric lenses, they are specifically designed to work in the infrared wavelength range. ZnSe infrared aspheric lenses are used in various applications such as thermal imaging, infrared spectroscopy, laser systems, and infrared cameras. They are particularly beneficial in applications where high-resolution imaging and precise focusing are required.
