LB4837 UV Fused Silica Bi-Convex Lens; Dia:1 in; f=250.0 mm Uncoated

The LB4837 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 1 inch and a focal length of 250.0 mm, is designed for use in a variety of applications that require precise optical manipulation.

The lens is made of UV Fused Silica, a material known for its excellent transmission properties across a wide range of wavelengths, including the ultraviolet region. This makes 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 performance on its own.

The lens geometry is spherical, with both surfaces curved outwards (convex). The radius of curvature for the first surface is 229.6 mm, while for the second surface it is -229.6 mm. This bi-convex design helps to minimize spherical aberration, ensuring that the lens focuses light accurately. The lens has an effective focal length (EFL) of 250.0 mm and a back focal length (BFL) of 249.1 mm.

The lens has a thickness of 2 mm at the edge and 2.7 mm at the center. This slight curvature is designed to reduce edge thickness and improve the overall performance of the lens. The lens is circular in shape, making it compatible with a wide range of optical systems.
