Cf-pc-38.1-76 38.1 mm Dia. CaF2 Plano-Concave Lens; EFL=-76.2mm Uncoated
This is a plano-concave lens made from Calcium Fluoride (CaF2) material, sourced from Alkor Technologies. The lens has a diameter of 38.1 mm and a center thickness of 2.5 mm. The effective focal length (EFL) of this lens is -76.2mm, indicating that it is a diverging lens.
The lens is uncoated, which means it does not have any additional layers to protect it or modify its optical properties. This could make it more susceptible to environmental damage and may affect its performance in certain applications.
The lens is designed for use at a wavelength of 5000 nm. It is spherical in shape, with a radius of curvature (R1) of -30.698 mm for the curved surface. The inner and outer radii are both 0, indicating that this lens does not have any additional shaping or curvature on its edges.
