The LF4624-UV is a spherical lens with a concave-convex base shape and a circular design, sourced from the reputable vendor Thorlabs. This lens boasts a diameter of 25.4 mm and a center thickness of 3.5 mm, with an edge thickness of 4.4 mm. The effective focal length (EFL) is -200 mm, and the back focal length (BFL) is -198.5 mm.
The lens is made from UVFS material with the ID 1965, specifically designed for use in the ultraviolet spectrum, between 245 and 400 nm. It features a coating on both the front and back surfaces, denoted as 'tho uv uv arc 245400', which further enhances its performance in the UV range.
This lens is a negative meniscus lens, meaning it has a concave front surface and a convex rear surface. The inner and outer radii are both 0, and the front and back radii of curvature are 150 mm and 56.6 mm, respectively.
The lens's geometry and material make it an ideal choice for applications requiring high-performance UV optics. Its detailed specifications, as provided by Thorlabs, ensure that users can make informed decisions when selecting optical components for their specific needs.
