Lithium Fluoride LiF Infrared Optics For UV-Sources, Receivers and Eximer Lasers
Lithium Fluoride has high transmittance in the UV region (120nm - 400nm) and is used in a range of components in UV-sources, receivers and eximer lasers. Windows, polarizers and lenses benefit from LiF as a substrate.
Care should be taken with LiF material due to its weakness when expeosed to sudden changes in temperature. Non-standard AR coatings are used when coating LiF material.
BonTek provides optical LiF material in single-crystal optical quality, fabricated to order.
