Cf-pc-25.4-63 25.4 mm Dia. CaF2 Plano-Concave Lens; EFL=-63.5mm Uncoated

This is a plano-concave lens, type of spherical lens, sourced from Alkor Technologies. It features a base shape of a circle and is designed for use in spherical geometry. The lens has a diameter of 25.4 mm and a center thickness of 2 mm. The effective focal length (EFL) of this lens is -63.5 mm, indicating that it is a diverging lens.

The lens is made of Calcium Fluoride (CaF2) material, specifically identified as "caf2 mal-1963". This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The 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 the performance of the lens can vary depending on the wavelength of the light it is intended to refract or focus.

This lens is currently in stock and more information about it can be found on the vendor's website through the provided weblink.
