LB4879-B UV Fused Silica Bi-Convex Lens; Dia:1 in; f=35.0 mm ARC 650-1050nm

The LB4879-B is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties across a broad 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 the 650-1050nm wavelength range, making it suitable for a wide array of optical applications.

The lens geometry features a center thickness of 7.4 mm and an edge thickness of 1.8 mm, providing a balance between optical performance and mechanical robustness. The radii of curvature for the front and back surfaces are 31 mm and -31 mm, respectively, resulting in a back focal length of 32.4 mm. The lens is spherical in shape, ensuring excellent image quality and low distortion.

The LB4879-B is coated with Thorlabs BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, enhancing its transmission capabilities and reducing unwanted reflections. This coating is designed to operate across the 650-1050nm range, making the lens highly efficient in the specified wavelength band.
