Cf-pc-50.8-200 50.8 mm Dia. CaF2 Plano-Concave Lens; EFL=-200mm Uncoated
The Cf-pc-50.8-200 is a 50.8 mm diameter Plano-Concave Lens made from Calcium Fluoride (CaF2) material, sourced from Alkor Technologies. This lens is designed with a base shape of a circle and features a spherical geometry. The lens's center thickness is 3 mm, and it has an effective focal length (EFL) of -200 mm, making it a diverging lens.
The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on both sides. The radius of curvature (R1) for the curved surface is -80.54 mm. This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties.
The lens is designed to operate at a wavelength of 5000 nm. It is important to note that this lens is uncoated, which means it may not perform optimally in certain applications where coatings are typically used to enhance performance, such as reducing surface reflections or increasing transmission.
