LB4282 UV Fused Silica Bi-Convex Lens; Dia:1 in; f=200.0 mm Uncoated

The LB4282 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 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 to focus light. The first surface has a radius of curvature of 183.6 mm, while the second surface has a radius of -183.6 mm. This bi-convex design provides a large field of view and low spherical aberration, making it suitable for imaging and beam shaping applications.

The lens has a thickness of 2 mm at the edge and 2.9 mm at the center. This ensures rigidity and durability, while also minimizing optical distortions. The effective focal length (EFL) of the lens is 200 mm, and the back focal length (BFL) is 199 mm. The inner and outer radii are 0 mm, indicating a uniform curvature across the lens surface.
