LB4879 UV Fused Silica Bi-Convex Lens; Dia:1 in; f=35.0 mm Uncoated

The LB4879 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 35.0 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 exceptional transparency across a broad spectrum, including the ultraviolet region. This makes the LB4879 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 high-quality base material ensures reliable performance.

The lens geometry is spherical, with both surfaces curved outwards (convex). The first surface has a radius of curvature of 31 mm, while the second surface has a radius of -31 mm. This bi-convex design helps to minimize spherical aberration, ensuring that the lens focuses light accurately. The lens has a central thickness of 7.4 mm and an edge thickness of 1.8 mm, providing structural rigidity while maintaining a low profile.

The lens is circular in shape, with a diameter of 25.4 mm. This, coupled with its thin profile, makes it compatible with various optical systems and setups. The effective focal length (EFL) of the lens is 35 mm, which, along with its diameter, determines the lens's field of view and magnification capabilities.
