LB4553-A UV Fused Silica Bi-Convex Lens; Dia:2 in; f=75.0 mm ARC 350-700nm
The LB4553-A is a high-quality bi-convex lens made from UV fused silica, designed for use in the 350-700nm wavelength range. This lens, sourced from Thorlabs, is a spherical lens with a base shape of a circle. It features a diameter of 2 inches (50.8mm) and a thickness at the edge of 2.5mm, while the center thickness measures 12.5mm.
The lens has an effective focal length (EFL) of 75mm, with a front radius (R1) of 67mm and a back radius (R2) of -67mm. The back focal length (BFL) is 70.6mm. The lens does not have any inner or outer radius specified.
The lens is coated with THo A Bbar on both the front and back surfaces, providing anti-reflection properties. This coating is specifically designed for the 350-700nm wavelength range. The lens is available in stock and can be purchased directly from the vendor's website.
