LB4915-A UV Fused Silica Bi-Convex Lens; Dia:0.5 in; f=50.0 mm ARC 350-700nm

The LB4915-A is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens is specifically designed for use in the ultraviolet (UV) spectrum, with a focal length of 50.0 mm and a diameter of 0.5 inches.

The lens is made from UV fused silica, a material known for its excellent transparency in the UV range, making it ideal for applications that require high-performance UV transmission. The bi-convex design, featuring radii of curvature of 45.6 mm on both surfaces, ensures excellent image quality and low spherical aberration.

The lens has a center thickness of 2.7 mm and an edge thickness of 1.8 mm, providing robustness and durability. The anti-reflection coating on both the front and back surfaces, with a specified arc of 350-700 nm, further enhances the lens's performance by reducing unwanted reflections and increasing transmission.

This lens is a versatile and reliable choice for a wide range of UV optical systems, offering high-quality imaging and transmission in the UV spectrum. It is currently in stock, according to the vendor's website, making it readily available for immediate use.
