PW0511CF 0.5 in Dia. Calcium Fluoride Round Plane Optical Window; t=3 mm Uncoated

The PW0511CF is a 0.5-inch diameter Calcium Fluoride (CaF2) Round Plane Optical Window, uncoated, with a thickness of 3 mm, sourced from Laser Components. This optical window is a flat, circular substrate designed for use in various optical systems, particularly where high transmission in the ultraviolet, visible, and near-infrared regions is required.

The window's base shape is circular, with a diameter of 12.7 mm, making it compatible with a wide range of optical components. The thickness of 3 mm provides sufficient structural integrity while minimizing optical distortion. The uncoated surface ensures high damage threshold and low scatter, making it suitable for high-power laser applications.

The material ID, caf2 mal-1963, indicates that this window is made of Calcium Fluoride, a material known for its excellent optical properties, including high transparency and a wide transmission range from 130 nm to 7 µm. The wavelength of 632.8 nm suggests its potential use in helium-neon (HeNe) laser systems.

The window's shape is that of a thin lens, which minimizes its impact on the overall optical system while providing the necessary protection and isolation for the optical components. The absence of a coating implies that the window has natural properties, making it suitable for applications where coating might introduce unwanted effects.
