CaF2-W-31.75x1 31.75 mm Dia. CaF2 Flat Window; t=1mm Uncoated

This is a flat window made of Calcium Fluoride (CaF2) with a diameter of 31.75 mm and a thickness of 1 mm. It is sourced from Alkor Technologies, a reputable vendor in the optical industry. The window is uncoated, which means it does not have any additional layers to enhance or alter its optical properties.

The CaF2 material is identified as "caf2 mal-1963" in the vendor's catalog. This specific type of CaF2 is known for its excellent transparency in the ultraviolet, visible, and infrared regions of the spectrum. It is often used in applications where high transmission and low absorption are required.

The window has a circular base shape and a thin lens shape. It is designed to be used in environments where there is a need for a clear view or transmission of light with minimal distortion. The window's flat geometry ensures that it does not cause any significant curvature or refraction of light.

The window is suitable for use with a wavelength of 633 nm. This wavelength falls within the visible spectrum, indicating that this window is suitable for use in applications involving visible light.
