LA5817-E 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=100mm 2-5µm

The LA5817-E is a Plano-Convex lens with a diameter of 25.4 mm, designed for use with a wavelength of 588 nm. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens is made of Calcium Fluoride (CaF2) with the material ID mal-1963, a material often used in optical applications due to its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.

The lens features an effective focal length (EFL) of 100 mm, making it suitable for a wide range of optical systems. The front and back surfaces of the lens are coated with tho ecaf2arc20005000, a broadband anti-reflection coating designed to reduce surface reflections and improve transmission. The lens has a thickness of 2 mm at the edge and 3.9 mm at the center, providing structural rigidity while maintaining a low profile.

The geometry of the lens is spherical, with a radius of curvature of 43.4 mm for the convex surface. The inner and outer radii are both zero, indicating a planar surface on the opposite side. This lens is part of Thorlabs' extensive catalog of optical elements, which includes a wide variety of lenses, mirrors, beam splitters, and other components.
