LA4874-A UVFS Plano-Convex Lens; Dia:1 in; f=150 mm ARC 350-700nm
The LA4874-A 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 ultraviolet to visible spectrum, specifically at a wavelength of 587.6 nm.
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 2 mm at the edge and 3.2 mm at the center. The effective focal length (EFL) of this lens is 150.5 mm, and the back focal length (BFL) is 148.4 mm. The inner and outer radii are 0, indicating a uniform curvature.
The LA4874-A lens is made from UVFS material, identified as MAL-1965. It is coated on both the front and back surfaces with a coating type described as "tho a bbar". This coating is designed to enhance the lens's performance in the specified wavelength range.
