    Double Convex (Bi-Convex) Spherical Lens, UV Fused Silica, Finite Imaging Lens Overview: Double-Convex (DCX) Lens, also referred to as bi-convex lens, has two positive, symmetrical faces with equal radii on both sides. These lenses are generally recommended for finite imaging applications. Bi-convex lenses are most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object distances (conjugate ratio) is between 0.2 and 5. Star
