LB4972-A UV Fused Silica Bi-Convex Lens; Dia:2 in; f=250.0 mm ARC 350-700nm

The LB4972-A is a high-quality bi-convex lens made from UV fused silica, a material known for its excellent transmission properties in the ultraviolet range. This lens, with a diameter of 2 inches and a focal length of 250.0 mm, is designed for use in applications where high-precision optics are required.

The lens features a spherical shape, with both surfaces curved to focus light. The first surface has a radius of curvature of 229.1 mm, while the second surface has a radius of -229.1 mm. This design results in an effective focal length (EFL) of 250.0 mm and a back focal length (BFL) of 248 mm. The lens has a center thickness of 5.8 mm and an edge thickness of 3 mm, providing robustness and durability.

The LB4972-A is coated with Thorlabs' Anti-Reflection Coating (ARC), designed for the 350-700 nm range. This coating reduces surface reflections, improving light transmission through the lens. The coating is applied to both the front and back surfaces of the lens.

This lens is sourced from Thorlabs, a leading vendor in the field of optical components. According to the vendor's information, the lens is in stock, ensuring quick delivery times.
