Lithium Fluoride Rectangular Windows

Lithium Fluoride Windows（rectangular）

Lithium fluoride rectangular window sheets have good optical properties, with a rectangular shape, used to separate the environment on both sides, isolating the interior and exterior of the instrument, thereby protecting the internal components. It has high transmittance and reflectivity in the ultraviolet and infrared bands. Lithium fluoride has a low refractive index in infrared materials, with a transmission spectrum range of 120nm-7000nm. It is used for lenses, prisms, and windows in thermal imaging, aerospace optics, and excimer laser optical systems. Micron optics can provide different types of window sheets such as circular, rectangular, wedge-shaped, perforated, and stepped sheets.
