Cf-pc-50.8-76 50.8 mm Dia. CaF2 Plano-Concave Lens; EFL=-76.2mm Uncoated
This is a plano-concave lens from Alkor Technologies, featuring a diameter of 50.8 mm and a center thickness of 3 mm. The lens is made of Calcium Fluoride (CaF2) with the Mal-1963 material ID, known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.
The lens has a negative focal length (EFL) of -76.2 mm, making it suitable for use in applications that require light convergence or divergence. The inner and outer radii are both zero, indicating a plano-concave geometry. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.
This lens is in stock and available for purchase on the Alkor Technologies website. It is a versatile optical component that can be used in various applications, including but not limited to, laser systems, beam shaping, and optical imaging.
