Lithium Fluoride Wedge Windows

Lithium fluoride wedge windows have good optical properties and can be used as window pieces to separate the environment on both sides, isolating the interior and exterior of the instrument, thereby protecting internal components. It can also be used to change the deflection path of light, with high transmittance and reflectivity in the ultraviolet and infrared bands. Lithium fluoride has a low refractive index in infrared materials, and its transmission spectrum ranges from 120nm to 7000nm. Lithium fluoride wedge windows come in various sizes and specifications to meet different application needs. Can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
