Description
Calcium Fluoride (CaF2) Crystals are renowned for their exceptional optical properties, making them a popular choice in various high-performance applications. These crystals are particularly noted for their broad transparency range, spanning from the ultraviolet (UV) to the infrared (IR) spectrum. This unique characteristic allows CaF2 to be effectively used in a wide array of optical components, where clarity and precision are paramount.
One of the standout features of CaF2 is its ability to maintain transparency across an extensive wavelength range, approximately from 0.13 to 10 micrometers. This broad spectrum makes it an ideal material for spectroscopic windows, where accurate light transmission is critical. Additionally, pure grades of Calcium Fluoride are highly sought after for their utility in UV applications, particularly as windows for UV Excimer lasers. These lasers are integral in various scientific and industrial processes, where precision and reliability are crucial.
The optical quality of CaF2 is further highlighted by its excellent surface properties, including scratch resistance and minimal dig, ensuring durability and longevity in demanding environments. The material's flatness and parallelism specifications ensure that it meets the rigorous standards required for high-precision optical systems. Overall, Calcium Fluoride crystals are a versatile and indispensable component in the optics industry, valued for their exceptional performance and adaptability across a range of applications.
