LB4879-A UV Fused Silica Bi-Convex Lens; Dia:1 in; f=35.0 mm ARC 350-700nm

The LB4879-A is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties across a wide spectrum, including the ultraviolet range. This lens, with a diameter of 1 inch and a focal length of 35.0 mm, is designed for use in applications where high-performance optical elements are required.

The lens features a spherical geometry, with radii of curvature of 31 mm for the first surface and -31 mm for the second. This design results in an effective focal length of 35 mm and a back focal length of 32.4 mm. The lens has a central thickness of 7.4 mm and an edge thickness of 1.8 mm, providing robustness and durability.

The LB4879-A is coated with a broadband anti-reflection coating, optimized for the 350-700 nm range. This coating reduces surface reflections, enhancing the lens's transmission capabilities and overall performance. The lens is sourced from Thorlabs, a leading vendor known for its high-quality optical components.
