112-1517E 50.8 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens
The 112-1517E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens has a base shape of a circle and a diameter of 50.8 mm. The lens's thickness at the edge is 5.7 mm, while its center thickness is 3.1 mm. The effective focal length (EFL) of this lens is -250 mm, indicating its concave nature.
The lens's first radius of curvature (R1) is -118.9 mm, and it does not have an inner radius. The outer radius is also not specified, which is common for plano-concave lenses as they typically have a flat outer surface.
This lens is made from UVFS MAL-1965 material, specifically designed for use with a wavelength of 355 nm. The lens does not have any coating, which is indicated by the empty 'coating' field in the item data.
