Hand-held Magnifiers: AplanticThe purpose of the Aplantic Lens is to correct spherical aberration. In an ideal optical system, all rays of light from a point in the object plane would converge to the same point in the image plane, forming a clear image. The influences which cause different rays to converge to different points are called aberrations. Eschenbach created the Aplantic lens with the concept that all of the rays emitted from one point come to a single focus in a corresponding point - offering the best optics available in magnifiers. The aplanatic lens is made of a high quality PXM® lightweight lens system consisting of two plano-convex lenses that give a clearly defined, distortion-free image. |
