The Double Convex Lenses are made with an identical convex surface on both sides of the lens. The Double Convex lenses have positive focal lengths and form both real and virtual images. This lenses are primarily used for imaging at close to 1:1, illustrates their function. The convex surfaces of approximately equal to the radius of curvature. As both convex surfaces contribute to the magnifying power, these lenses are available with useful for collecting and refocusing light from a small beams in applications where the length of an optical train spot quality. We provide a large variety kinds of specifications according to clients’ request or Personalized customization for precision grade Double Convex lenses with tighter tolerances . Our DCV lenses are available in a range of coating or substrate options. Anti-reflection coatings range from the Ultraviolet (UV) to the Infrared (IR).
