Cf-pc-25.4-100 25.4 mm Dia. CaF2 Plano-Concave Lens; EFL=-100mm Uncoated
This is the Cf-pc-25.4-100, a 25.4 mm diameter Plano-Concave Lens made from Calcium Fluoride (CaF2) material. The lens is sourced from Alkor Technologies and is currently in stock, as indicated by its valid weblink status.
The lens features a spherical shape, with a base shape of a circle. It has a center thickness of 2 mm and an effective focal length (EFL) of -100 mm, making it a concave lens. The inner and outer radii are 0, and the first radius of curvature (R1) is -40.35 mm.
The lens is designed to work with a wavelength of 5000 nm. It is uncoated, which means it does not have any additional layers to enhance its optical properties. The CaF2 material, also known as mal-1963, is a common choice for its excellent transparency in the ultraviolet, visible, and infrared regions of the spectrum.
