LB4030-A UV Fused Silica Bi-Convex Lens; Dia:1 in; f=40.0 mm ARC 350-700nm

The LB4030-A 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 1 inch and a focal length of 40.0 mm, making it suitable for a wide range of optical applications.

The lens is crafted from UV fused silica, a material known for its excellent optical properties, including high transparency across a broad spectrum (350-700nm) and a low coefficient of thermal expansion. This makes the LB4030-A an ideal choice for applications that require high precision and stability, such as laser systems and spectroscopy.

The lens features a spherical geometry, with radii of curvature of 35.7 mm for the first surface and -35.7 mm for the second surface. This geometry, combined with the lens's high-quality anti-reflection coating (ARC), ensures efficient light transmission and minimal optical loss. The ARC is designed to reduce surface reflections, enhancing the lens's performance in high-power applications.

The LB4030-A has a center thickness of 6.7 mm and an edge thickness of 1.8 mm, providing excellent mechanical stability. The lens's base shape is circular, allowing for versatile use in various optical setups.
