LB4710-C UV Fused Silica Bi-Convex Lens; Dia:2 in; f=300.0 mm ARC 1050-1700nm
The LB4710-C is a high-quality bi-convex lens made from UV fused silica, a material known for its excellent transmission properties across a wide range of wavelengths. This lens, sourced from Thorlabs, features a diameter of 2 inches (50.8 mm) and a focal length of 300.0 mm, making it suitable for a variety of optical applications.
The lens's geometry includes a thickness of 3 mm at the edge and 5.4 mm at the center, with a back focal length of 298.2 mm. The radii of curvature for the front and back surfaces are 275.2 mm and -275.2 mm, respectively. The lens's effective focal length (EFL) is 300 mm, and it does not have any inner or outer radius.
The LB4710-C is coated with Thorlabs' Broadband Anti-Reflection Coating (BBAR), which is designed to minimize surface reflections and optimize transmission across the 1050-1700 nm range. This coating is applied to both the front and back surfaces of the lens.
