CaF2-W-25.4x6 25.4 mm Dia. CaF2 Flat Window; t=6mm Uncoated

The CaF2-W-25.4x6 is a flat window type optical element, sourced from Alkor Technologies. This component is circular in base shape with a diameter of 25.4 mm and a thickness of 6 mm. The material ID for this item is "caf2 mal-1963".

This window is made of Calcium Fluoride (CaF2), a material known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. It is often used in applications where high transmission and excellent optical quality are required.

The CaF2-W-25.4x6 is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired. However, it may not be suitable for environments with high levels of dust or other particulate matter, as the lack of a protective coating could lead to surface damage.

The window is designed in the shape of a thin lens, which can be beneficial in applications where a flat, transparent surface is required, but a slight focusing effect is also desired. This could include uses in beam shaping, collimation, or simple imaging systems.

According to the vendor's website, this item is currently in stock, making it a readily available option for those in need of a high-quality Calcium Fluoride window.
