LA5370-E 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=40mm 2-5µm
The LA5370-E is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, manufactured by Thorlabs. This lens is designed for use with a wavelength of 588 nm and features a focal length of 40 mm. The lens is made of Calcium Fluoride (CaF2) with a refractive index of 1.434 at 588 nm.
The lens has a thickness of 2 mm at the edge and 7.5 mm at the center. The front and back surfaces of the lens are coated with AR coating (tho ecaf2arc20005000) to reduce reflection and improve transmission. The lens is available in stock and can be purchased directly from the vendor's website.
This lens is suitable for use in various applications that require a high level of optical performance, such as imaging systems, beam shaping, and laser applications. The high transmission of CaF2 in the visible and near-infrared regions makes it an ideal material for lens manufacturing in these applications.
