LB4913-B UV Fused Silica Bi-Convex Lens; Dia:1 in; f=125.0 mm ARC 650-1050nm

The LB4913-B UV Fused Silica Bi-Convex Lens is a high-quality optical component designed for use in a wide range of applications. This lens, sourced from Thorlabs, boasts a diameter of 1 inch (25.4 mm) and a focal length of 125.0 mm, making it a versatile choice for many optical systems.

The lens is made from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a broad spectrum (650-1050 nm) and a low coefficient of thermal expansion. This makes the LB4913-B particularly suitable for applications that require high precision and stability, such as laser systems, interferometry, and imaging applications.

The lens features a bi-convex geometry, with radii of curvature of 114.5 mm for the first surface and -114.5 mm for the second surface. This geometry provides a large numerical aperture, enhancing the lens's light-gathering capability and improving its performance in high-resolution applications.

The LB4913-B is coated with Thorlabs BBAR coating on both the front and back surfaces. This coating reduces reflection and increases transmission across the specified wavelength range, further enhancing the lens's performance.
