LB4879-C UV Fused Silica Bi-Convex Lens; Dia:1 in; f=35.0 mm ARC 1050-1700nm
The LB4879-C is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties across a wide range of wavelengths. This lens, with a diameter of 1 inch and a focal length of 35.0 mm, is designed for use in the ARC 1050-1700nm range, making it suitable for various applications in the optical spectrum.
The lens features a base shape of a circle, with a thickness of 1.8 mm at the edge and 7.4 mm at the center. The effective focal length (EFL) is 35 mm, and the back focal length (BFL) is 32.4 mm. The radii of curvature for the first and second surfaces are 31 mm and -31 mm, respectively. The lens has no inner or outer radius, indicating a uniform curvature across the surface.
The LB4879-C is coated with Thorlabs' Broadband Anti-Reflection coating, which is designed to minimize surface reflections and improve transmission. This coating is applied to both the front and back surfaces of the lens. The lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
