LB4842-A UV Fused Silica Bi-Convex Lens; Dia:2 in; f=200.0 mm ARC 350-700nm

The LB4842-A is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties across a wide spectrum, particularly in the ultraviolet range. This lens, with a diameter of 2 inches and a focal length of 200.0 mm, is designed for use in applications where high-performance optical elements are required.

The lens features a spherical geometry, with radii of curvature of 183 mm for the first surface and -183 mm for the second. This design results in a back focal length of 197.7 mm. The lens has a central thickness of 6.5 mm and an edge thickness of 3 mm, providing robustness and durability.

The LB4842-A is coated with Thorlabs' Anti-Reflection Coating (ARC), designed for the 350-700 nm range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing the amount of light transmitted through the lens. The coating is applied to both the front and back surfaces of the lens.

This lens is sourced from Thorlabs, a leading vendor in the field of optical components. According to the vendor's information, the lens is currently in stock, ensuring quick delivery times. The item data also provides a link to the vendor's website for further information and purchasing options.
