LB4743-B UV Fused Silica Bi-Convex Lens; Dia:5 mm; f=10.0 mm ARC 650-1050nm
The LB4743-B is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens boasts a diameter of 5 mm and a focal length of 10.0 mm, making it a versatile choice for a wide range of applications.
The lens is crafted from UV Fused Silica, a material with a high Abbe number, ensuring low dispersion and excellent optical performance. The base shape of the lens is circular, and it features a spherical geometry, with radii of curvature of 8.8 mm and -8.8 mm for the first and second surfaces, respectively. The lens has a center thickness of 2.2 mm and an edge thickness of 1.5 mm, providing robustness and durability.
The LB4743-B is coated with Broadband Anti-Reflection Coatings (BBAR), specifically designed for the 650-1050 nm wavelength range. This coating enhances the lens's transmission capabilities, reduces surface reflections, and increases overall system efficiency.
