This is a flat window made from Calcium Fluoride (CaF2) with a diameter of 101.6 mm and a thickness of 8 mm. The item, sourced from Alkor Technologies, is a circular window, specifically designed for use in optical systems. It is uncoated, providing a clear, unaltered view of the light path.
The window is made from a single piece of CaF2, a material with a Maltese Cross interference figure, as per the Mal-1963 specification. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. It has a refractive index of 1.43 at 589.3 nm and a density of 3.18 g/cm3.
The window's thin lens shape is designed to minimize optical aberrations and distortions, making it ideal for use in high-precision optical systems. It is in stock and ready for immediate use or integration into your optical system.
