LB4972-C UV Fused Silica Bi-Convex Lens; Dia:2 in; f=250.0 mm ARC 1050-1700nm

The LB4972-C 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 the reputable vendor Thorlabs, boasts a diameter of 2 inches and a focal length of 250.0 mm, making it a versatile choice for many optical systems.

The lens is constructed from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a broad spectrum (1050-1700nm). This makes the LB4972-C particularly suitable for applications that require high-performance in the ultraviolet and near-infrared regions.

The lens features a Spherical shape, with both faces being Convex. The first face has a radius of curvature (R1) of 229.1, while the second face has a radius of curvature (R2) of -229.1. This bi-convex design helps to minimize spherical aberration, ensuring optimal image quality.

The lens has a center thickness of 5.8 and an edge thickness of 3. It is coated with a Broadband Anti-Reflection coating (BBAR) on both the front and back surfaces, which enhances its transmission capabilities and reduces unwanted reflections.

In terms of geometry, the lens has an inner radius of 0 and an outer radius of 0. The Effective Focal Length (EFL) is 250.0 mm, and the Back Focal Length (BFL) is 248 mm. This information is crucial for accurate system design and alignment.
