PW0525CF 0.5 in Dia. Calcium Fluoride Round Plane Optical Window; t=0.25 in Uncoated

The PW0525CF is a 0.5-inch diameter, calcium fluoride (CaF2) round plane optical window, with a thickness of 0.25 inches, offered by Laser Components. This uncoated window is designed for use in various optical systems, particularly where high transmission in the ultraviolet, visible, and near-infrared regions is required.

The window features a flat, circular geometry with a diameter of 12.7 millimeters and a thickness of 6.35 millimeters. This thin lens shape allows for minimal optical distortion and ease of integration into various optical setups. The window is made of calcium fluoride (CaF2), a material with a wide transmission range from 130 nm to 7 μm, making it suitable for a broad range of applications.

The PW0525CF is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this also means it can be easily customized with various coatings to suit specific application needs. The window's material ID, "caf2 mal-1963", can be used for reference when selecting appropriate coatings.

The wavelength specified for this item is 632.8 nm, which is within the visible light spectrum. This suggests that the window is particularly suitable for applications involving visible light, such as laser systems or imaging applications.
