The LB4003-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens is part of their extensive catalog of optical elements, which 3DOptix integrates into its advanced optical simulation software.
The lens is spherical in shape, with a base shape of a circle. It has a diameter of 0.5 inches (12.7 mm) and a thickness at the edge of 1.8 mm. The center thickness is 3.3 mm, and the effective focal length (EFL) is 30 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 (BFL) of 28.8 mm.
The lens is made of UV fused silica, a material with the material ID "uvfs mal- 1965". This material is known for its excellent transparency in the ultraviolet (UV) region, making this lens suitable for applications that require UV transmission.
The lens features anti-reflection (AR) coatings on both the front and back surfaces. These coatings are designed to operate in the 1050-1700 nm wavelength range, further enhancing the lens's performance in the UV region.
