LB4821 UV Fused Silica Bi-Convex Lens; Dia:2 in; f=100.0 mm Uncoated

The LB4821 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 2 inches and a focal length of 100.0 mm, is designed for use in a wide range of applications that require excellent optical performance.

The lens is made of UV Fused Silica, a material known for its high transparency in the ultraviolet region, making it an ideal choice for applications that involve UV light. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, its base material provides excellent optical performance, making it a reliable choice for many applications.

The lens geometry is spherical, with a radius of curvature of 90.4 mm for the first surface and -90.4 mm for the second surface. This bi-convex design provides a large field of view and low spherical aberration, making it suitable for imaging applications. The lens has a central thickness of 10.3 mm and an edge thickness of 3 mm, providing mechanical stability and resistance to damage.

The lens has an effective focal length (EFL) of 100.0 mm, which is the distance from the lens to the focal point when the lens is used in air. This EFL, combined with the lens diameter, determines the lens's angular field of view, which is an important consideration for many applications.
