This item is a flat window, specifically a CaF2-W-50.8x5, sourced from Alkor Technologies. It features a circular base shape with a diameter of 50.8 mm and a thickness of 5 mm. The material ID for this component is "caf2 mal-1963".
The window is made of Calcium Fluoride (CaF2), a common material in optical applications due to its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. This makes it an ideal choice for applications that require high transmission across a wide range of wavelengths.
The item 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 maintaining the native properties of the material is crucial.
The window is in stock and available for purchase. For more detailed information, please refer to the vendor's website at http://www.alkor.net/CaF2_windows.html.
