LD5788 12.7 mm Dia. CaF2 Double-Concave Lens; EFL=-25mm Uncoated

The LD5788 is a high-quality spherical lens from Thorlabs, featuring a concave-concave base shape and a circular geometry. This lens is designed with a 12.7 mm diameter and a center thickness of 3 mm, making it suitable for a wide range of optical applications. The effective focal length (EFL) of this lens is -25 mm, indicating its diverging nature, which is further emphasized by its negative sign.

The LD5788 lens is made from Calcium Fluoride (CaF2) material, specifically identified as "caf2 mal-1963" in the material database. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

This lens is designed to work with a wavelength of 588 nm, making it suitable for applications that operate within or near this wavelength. The LD5788 is currently in stock and available for immediate purchase from the vendor's website, as indicated by its valid weblink status.
