LB4854 UV Fused Silica Bi-Convex Lens; Dia:0.5 in; f=20.0 mm Uncoated

The LB4854 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 0.5 inches and a focal length of 20.0 mm, is designed for use in a wide range of applications that require precise optical manipulation.

The lens is made of UV Fused Silica, a material known for its excellent optical properties, including high transparency in the ultraviolet region. This makes the LB4854 particularly suitable 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 17.7 mm, while for the second surface it is -17.7 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 20.0 mm, which is the distance from the lens at which a collimated beam of light will be focused to a spot.

The lens has a central thickness of 2.8 mm and an edge thickness of 1.8 mm. This provides a good balance between mechanical strength and optical performance. The lens is circular in shape, making it compatible with a wide range of optical systems.
