OPCF-20C02-P 20 mm Dia. CaF2 Round Flat Window; t=2 mm Uncoated

The OPCF-20C02-P is a high-quality optical window from OptoSigma, designed for use in ultraviolet and infrared laser applications. This window features a base shape of a circle with a diameter of 20 mm, making it suitable for a wide range of optical systems.

The window is made from Calcium Fluoride (CaF2), a material with a Mal-1963 Material ID. This material is known for its excellent transparency in the ultraviolet, visible, and infrared regions of the spectrum, making it an ideal choice for laser applications. The window has a thickness of 2 mm, providing a good balance between strength and light transmission.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a natural surface is preferred. However, it's important to note that uncoated surfaces can be more susceptible to environmental factors such as dust and moisture, so appropriate handling and storage procedures should be followed.

The OPCF-20C02-P is currently in stock and available for purchase through the OptoSigma website. With its combination of high-quality materials, precise dimensions, and versatile applications, this window is a reliable choice for any optical system that requires a flat window in the ultraviolet and infrared spectrum.
