OPCFU-20C01-P 20 mm Dia. CaF2 Round Flat Window; t=1 mm Uncoated

The OPCFU-20C01-P is a high-quality optical window offered by OptoSigma, a leading vendor in the field of ultraviolet and infrared laser components. This window, designed for use with lasers of specific wavelengths, is a flat, circular window with a diameter of 20 mm and a thickness of 1 mm.

The window is made from Calcium Fluoride (CaF2), a material with the Mal-1963 ID, which is known for its excellent transparency in the ultraviolet and infrared regions of the spectrum. This makes the OPCFU-20C01-P an ideal choice for applications that require efficient transmission of light in these wavelength ranges.

The window's shape is that of a thin lens, which, despite its name, does not alter the path of light passing through it. Instead, this shape provides structural integrity while maintaining a minimal thickness to minimize optical distortion.

Notably, this particular model is uncoated. Coatings are often applied to optical components to enhance their performance, such as by reducing reflectivity or increasing durability. However, an uncoated window like the OPCFU-20C01-P can be advantageous in certain applications where a specific coating is not required or would interfere with the system's operation.
