LB4743-A UV Fused Silica Bi-Convex Lens; Dia:5 mm; f=10.0 mm ARC 350-700nm

The LB4743-A is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens, with a diameter of 5 mm, is specifically engineered for use in the ultraviolet (UV) spectrum, making it ideal for applications that require precise manipulation of UV light.

The lens features a focal length of 10.0 mm, providing a balance between a wide field of view and a focused beam. The bi-convex design, with radii of curvature of 8.8 mm for both the front and back surfaces, ensures minimal spherical aberration, resulting in high-quality, distortion-free images.

The lens is made from UV fused silica, a material known for its excellent transparency in the UV range. This material also offers high thermal stability and chemical resistance, making it suitable for use in harsh environments. The lens has a central thickness of 2.2 mm and an edge thickness of 1.5 mm, providing robustness and durability.

The LB4743-A is coated with Thorlabs' anti-reflection coating (ARC), designed for the 350-700 nm range. This coating reduces surface reflections, improving light transmission and enhancing the overall performance of the lens. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
