A biconvex lens has two outwardly convex spherical surfaces, usually with equal radii of curvature, a thick center and thin edges. It is a positive or converging lens that focuses parallel rays and is used in imaging, laser systems, microscopes and telescopes. Both surfaces are spherical and convex, with their centers of curvature on opposite sides of the lens. The usually symmetric structure provides positive optical power. It strongly focuses parallel light to form a real image. Compared with a single convex lens, the spherical biconvex design reduces spherical aberration by 30-40% for clearer imaging. It performs well over object to image distance ratios from 0.2:1 to 5:1 and is particularly suitable for 1:1 imaging. Spherical and chromatic aberrations remain and can affect image quality away from the paraxial region.
