LA4158-C UVFS Plano-Convex Lens; Dia:1 in; f=250 mm ARC 1050-1700nm
The LA4158-C UVFS Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 1 inch, is designed for use in the infrared spectrum, specifically between 1050nm and 1700nm.
The lens is spherical in shape, with a base shape of a circle. It features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The lens has a thickness of 2mm at the edge and 2.7mm at the center. The effective focal length (EFL) of this lens is 250.9mm, and the back focal length (BFL) is 249mm. The inner and outer radii are 0, indicating a flat inner surface and a curved outer surface.
The LA4158-C lens is made from UVFS material, identified as MAL-1965 in the material database. It comes with anti-reflection coating on both the front and back surfaces, specifically the THo C Bbar coating, which is designed to reduce surface reflections and increase transmission in the spectral range of 400-700nm.
