LA8862-E 25.4 mm Dia. Silicon Plano-Convex Lens; EFL=50mm 2-5µm
The LA8862-E is a Spherical Lens (Plano-Convex) with a circular base shape, sourced from the reputable vendor Thorlabs. This lens boasts a diameter of 25.4 mm and a thickness at the edge of 3.3 mm, while the center thickness measures 4 mm. The Effective Focal Length (EFL) is 50 mm, designed for use with a wavelength of 4000 nm.
The lens is constructed from Silicon, specifically Silicon Sal Vil 1957, and features a coating on both the front and back surfaces. The front coating is tho esiarc20005000, while the back coating is also tho esiarc20005000. This coating enhances the lens's performance and durability.
The lens's geometry is spherical, with an inner radius of 0 mm and an outer radius of 0 mm. The shape of the lens is plano-convex, meaning one side is flat (plano) and the other side is curved (convex). This design is often used to correct aberrations in optical systems.
The lens's web links are valid and indicate that it is in stock, making it readily available for your optical needs.
