LA4148-A UVFS Plano-Convex Lens; Dia:1 in; f=50 mm ARC 350-700nm
The LA4148-A UVFS Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field. This lens, with a diameter of 1 inch, is designed for use in the UV-VIS-NIR spectrum, specifically catering to wavelengths between 350nm and 700nm.
The lens is spherical in shape, with a plano-convex base type. The geometry of the lens includes a 25.4mm diameter, a 2mm thickness at the edge, and a 5.8mm thickness at the center. The effective focal length (EFL) of the lens is 50.2mm, and the back focal length (BFL) is 46.2mm. The inner and outer radii are 0mm, indicating a uniform curvature.
The LA4148-A lens is made from UVFS material, identified as MAL-1965 in the material database. It features anti-reflection coatings on both the front and back surfaces, specifically THo A BBAR coatings designed to minimize surface reflections and increase transmission in the 350-700nm range.
