LB4265 UV Fused Silica Bi-Convex Lens; Dia:1 in; f=150.0 mm Uncoated

The LB4265 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 150.0 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 transmission properties across a broad spectrum, including the ultraviolet range. 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 first surface has a radius of curvature of 137.5 mm, while the second surface has a radius of -137.5 mm. This bi-convex design helps to minimize spherical aberration, ensuring that the lens focuses light accurately. The lens has a central thickness of 3.2 mm and an edge thickness of 2 mm, providing robustness and durability.

The lens's effective focal length (EFL) is 150.0 mm, which is the distance from the lens at which a collimated beam of light will be focused to a spot. The back focal length (BFL) is 148.9 mm, which is the distance from the lens's rear surface to the focus of a collimated beam.
