CaF2-W-38.1x6 38.1 mm Dia. CaF2 Flat Window; t=6mm Uncoated

The CaF2-W-38.1x6 is a flat window type optical element, sourced from Alkor Technologies. This window, with a base shape of a circle, has a diameter of 38.1 mm and a thickness of 6 mm, making it suitable for various optical applications.

The material of this window is Calcium Fluoride (CaF2), specifically identified as "caf2 mal-1963" in the Material ID. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The wavelength of 633 nm, specified in the item data, falls within the visible light spectrum, indicating that this window is suitable for use with red light optical systems.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where maintaining the original optical properties of the material is crucial.
