LB4003-A UV Fused Silica Bi-Convex Lens; Dia:0.5 in; f=30.0 mm ARC 350-700nm
The LB4003-A is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties and chemical resistance. This lens, with a diameter of 0.5 inches and a focal length of 30.0 mm, is designed for use in the ARC 350-700nm range, making it suitable for a wide range of applications in the ultraviolet spectrum.
The lens geometry is spherical, with a center thickness of 3.3 mm and an edge thickness of 1.8 mm. The radii of curvature for the first and second surfaces are 27.1 mm and -27.1 mm, respectively, resulting in a back focal length of 28.8 mm. The lens has a circular base shape and is available from Thorlabs, a leading vendor in the optical components industry.
The LB4003-A is coated with Thorlabs' Anti-Reflection coating, which is designed to reduce surface reflections and increase transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
