Concave And Convex Lens


The Double Convex Lenses are made from BK7 material, which are manufactured 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. We also provide precision grade Double Convex lenses with tighter manufacturing tolerances


Biconvex lenses are used as magnifiers, objectives, condensing systems. Since both surfaces contribute to the power of biconvex lenses, they have shorter focal length than PCX lenses of equal diameter and surface radius. Lenses can be anti-reflection coated (please refer to the Coatings section).
