LB4453 UV Fused Silica Bi-Convex Lens; Dia:1 in; f=500.0 mm Uncoated

The LB4453 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 1 inch, is designed for use at a focal length of 500.0 mm, making it suitable for a wide range of optical applications.

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 the LB4453 an ideal choice for applications that require high transmission in the UV range.

The lens features a bi-convex geometry, meaning it has two spherical surfaces that are both convex. This design provides a high degree of focusing power, making the lens suitable for use in imaging systems, beam shaping, and other applications where precise focusing is required.

The LB4453 has a diameter of 25.4 mm and a thickness of 2 mm at the edge, with a center thickness of 2.4 mm. The effective focal length (EFL) of the lens is 500.0 mm, and the back focal length (BFL) is 499.2 mm. The radii of curvature for the first and second surfaces are 459.7 mm and -459.7 mm, respectively.

Notably, this lens is uncoated. While coatings can enhance the performance of optical components in certain applications, an uncoated lens can be advantageous in situations where broadband transmission is required, or where the user wishes to apply their own coating.
