LE4822 50.8 mm Dia. UVFS Positive Meniscus Lens; EFL=1000mm Uncoated
The LE4822 is a spherical lens with a convex-concave design, sourced from the reputable vendor Thorlabs. This lens boasts a 50.8 mm diameter and is fabricated from UVFS material, specifically identified as UVFS MAL-1965. The lens's base shape is circular, and it features a positive meniscus design.
The lens's geometry is meticulously crafted, with an edge thickness of 4.3 mm and a center thickness of 5 mm. The effective focal length (EFL) is 1000 mm, and the back focal length (BFL) is 995.6 mm. The first radius of curvature (R1) is 356.7 mm, while the second radius of curvature (R2) is 1580.2 mm. Notably, the lens does not have any inner or outer radius specified, indicating a uniform curvature.
The LE4822 is designed to operate at a wavelength of 588 nm. It does not come with any coating, which may affect its performance in certain applications. However, its uncoated status could be beneficial in scenarios where coating might introduce unwanted reflections or alter the optical properties.
