LB4879-UV 25.4 mm Dia. UVFS Double-Convex Lens; EFL=35mm 245-400nm

The LB4879-UV is a high-quality double-convex lens, boasting a diameter of 25.4 mm and a focal length of 35 mm. This lens is designed for use with ultraviolet light, specifically within the wavelength range of 245-400 nm, making it an ideal choice for applications in this spectrum.

This lens is sourced from Thorlabs, a trusted vendor known for its high-quality optical components. The lens is made from UVFS material, identified by the Material ID "uvfs mal- 1965", and features a double-convex shape with radii of curvature of 31 mm on both sides. The lens has a center thickness of 7.4 mm and an edge thickness of 2 mm, providing robustness and durability.

The LB4879-UV lens comes with broadband anti-reflection (BBAR) coatings on both the front and back surfaces, specifically designed for the UV range. These coatings help to minimize surface reflections, thereby improving transmission and enhancing the overall performance of the lens.
