LB4710-B UV Fused Silica Bi-Convex Lens; Dia:2 in; f=300.0 mm ARC 650-1050nm

The LB4710-B is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens boasts a diameter of 2 inches (50.8 mm) and a focal length of 300.0 mm, making it suitable for a wide range of optical applications.

The lens is made from UV fused silica, a material known for its excellent transmission properties across a broad spectrum, from 190 to 2000 nm. This makes the LB4710-B particularly suitable for applications that require high transmission in the ultraviolet (UV) range, such as UV spectroscopy or fluorescence microscopy.

The lens features a spherical geometry, with radii of curvature of 275.2 mm for the first surface and -275.2 mm for the second surface. This bi-convex design provides a large numerical aperture, enhancing the lens's light-gathering capability and improving its performance in high-resolution imaging applications.

The LB4710-B is coated with Thorlabs' BBAR (Broadband Anti-Reflection) coating, which is designed to minimize surface reflections and increase transmission across the lens's entire spectral range. This coating reduces the lens's overall reflectivity to less than 0.5% at normal incidence, ensuring optimal light transmission and reducing the need for additional anti-reflection components.
