LB4842 UV Fused Silica Bi-Convex Lens; Dia:2 in; f=200.0 mm Uncoated

The LB4842 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 200.0 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 in the same direction (convex-convex). The first surface has a radius of curvature of 183 mm, while the second surface has a radius of -183 mm. This specific curvature design allows for efficient light bending and focusing. The lens has a central thickness of 6.5 mm and an edge thickness of 3 mm, providing structural rigidity while maintaining a low profile.
