The LB4453-A is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens, with a diameter of 1 inch, is specifically designed for use in the ultraviolet (UV) spectrum, with a central wavelength of 588nm.
The lens is made from UV fused silica, a material known for its excellent transparency in the UV range, making it ideal for applications that require high-resolution imaging or precise focusing in this spectrum. The lens has a focal length of 500mm, indicated by the 'f=500.0 mm' in its name, which is a critical parameter in determining the lens's focusing power.
The lens features an anti-reflective (AR) coating on both surfaces, specifically designed for the 350-700nm range. This coating helps to minimize light loss due to reflection, thereby improving the overall efficiency of the optical system in which the lens is used. The coating also helps to reduce ghosting and flare, thereby enhancing the quality of the images produced.
The lens has a clear aperture of 1 inch, indicated by the 'Dia:1 in' in its name. The 'thickness edge' is 2mm, while the 'thickness center' is 2.4mm. The lens's geometry is spherical, with radii of curvature 'r1' and 'r2' being 459.7mm and -459.7mm, respectively. The back focal length (BFL) is 499.2mm.
