Plano-Convex Lenses

Plano-convex (PCX) lens is an optical lens with one plane face and one convex face, and a positive focal length, utilized for collecting, focusing collimated lights, collimating lights from a point source, or reducing the focal length of a lens group. Compared to Biconvex lenses,  Plano-convex lenses have two unidentical sides and therefore work best for an infinite absolute conjugate ratio (objective distance: image distance). However, plano-convex lenses still reduce spherical aberrations to a quite low extent when the absolute conjugate ratio is greater than 5:1. For conjugate ratio below 5:1, consider using plano-convex lenses in pairs or a biconvex lens.

Hangzhou Shalom EO offers Stocked and Custom  Plano-convex Lenses. While you can browse and shop Off-the-Shelf N-BK7 Plano Convex Lenses, Off-the-Shelf UVFS Plano Convex Lenses, Off-the-Shelf CaF2 Plano Convex Lenses, we also provide custom plano convex lenses made from a wide assortment of optical materials including sapphire, Flint Glass/BaF2/Ge/Si, etc. that are competent for various incorporation into emitters, detectors, imaging instruments, lasers, fiber optics, etc. Our N-BK7 plano-convex lenses contain an optional diameter range of 6-75mm, and a focal length range of 10-1000mm, while other dimensions and focal lengths could be customized. These lenses feature λ/4-λ irregularities and 40/20 scratch/dig. The UV Fused Silica plano-convex lenses highlight a high-precision version of lambda/10 irregularities and 10/5 S/D, or a normal version of  λ/4-λ irregularities and 40/20 S/D, the glass materials are sourced from Corning (Corning 7980-0F, Corning 7980-1D). Our CaF2 plano-convex lenses (standard) have diameters ranging from 12.7mm to 25.4mm and focal lengths ranging from 20mm to 1000mm, encompassing short focal lengths, mid-focal lengths, and long focal lengths.  Each piece of the lens will undergo strict inspection in Shalom EO’s in-house labs before dispatch to secure your interest. Our inspection procedure includes an in-process checking stage of the optical properties of lenses and a final test of coatings, dimension precisions, and the visual observation of scratch/dig, apertures, inclusions, etc.
