Double-Convex Spherical Lens

Double-Convex Lens, also named Bi-Convex Lens,composing of two convex surfaces, has a positive focal length. DCX Lens is most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5. It is used in beam expanders,projection optics systems, optical viewers applications etc.

We also supply kinds of plano-convex spherical lenses,plano-concave spherical lenses,bi-convex spherical lenses,bi-concave spherical lenses,Meniscus Spherical Lenses,special spherical lenses,achromatic spherical lenses,ball lenses,sphere lenses etc..
