LA5464-D 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=500mm 1.65-3µm

The LA5464-D is a Plano-Convex lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is fabricated from Calcium Fluoride (CaF2) material, specifically the Mal-1963 variant, which is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.

The lens has an effective focal length (EFL) of 500mm, which is a crucial parameter in determining the lens's magnification power. The EFL is the distance from the lens's center to the point at which a parallel beam of light would converge after passing through the lens.

The LA5464-D has a front coating of tho d bbar and a back coating of tho d bbar. Coatings are applied to the lens surfaces to enhance their performance by reducing reflection, increasing transmission, and protecting the lens from environmental hazards.

The lens has a thickness of 2mm at the edge and 2.4mm at the center. The curvature of the lens is defined by a radius of 216.9mm on the planar side. The lens is designed to operate within the wavelength range of 588µm.
