Abstract The disclosure is a microscopic lens comprising three component lenses with concave and convex conical sections which refract light rays. Rays emanating from an object pass through five conical surfaces, first being refracted outward and separated to form a ring image, and then being refracted inward and rejoined to form an enlarged image. There is one outward refraction as opposed to three inward refractions, and it is the difference between these refractions that produces magnification of the object. Magnification produced by one conical microscopic lens is small, so a number of lenses are used to form multi-stage microscopes in which magnification increases at an exponential rate. Thus, though the initial stage lens might produce a small magnification of only 4.5×, two stages will produce a magnification of 20×, three stages 91×, four stages 410×, etc. Eight stages produce a magnification in excess of 100,000×, which is in the range of magnification achieved by electron scanning microscopes. The use of multiple stages is possible because both the rays entering the lenses and the rays leaving the lenses are parallel.

A microscopic lens comprising three component lenses, with each component lens having one or two conical sections with surfaces which refract light rays at prescribed angles, with all conical sections of the component lenses being aligned on a common axis which is parallel to the light rays entering and emanating from the component lenses, with all surfaces of the component lenses not used for the refraction and transmission of light rays being opaque, (a) with a lower component lens being positioned above an object and having a concave conical section which receives parallel rays emanating from the object and refracts these rays outward from the common axis at a prescribed angle, and having a convex conical section which receives rays emanating from the concave conical section of the lower component lens and refracts these rays parallel to the common axis, thereby forming an annular image of the object, (b) with a middle component lens being above and adjacent to the lower component lens and having a convex conical section which receives rays emanating from the convex conical section of the lower component lens and refracts these rays inward toward the common axis, and having a concave conical section which receives rays emanating from the convex conical section of the middle component lens and refracts these rays inward toward the common axis, (c) and with an upper component lens being above and adjacent to the middle component lens and having a concave conical section which receives rays emanating from the concave conical section of the middle component lens and refracts these rays parallel to the common axis, forming an enlarged whole image of the object, and having a planar section which receives rays emanating from the concave conical section of the upper component lens and transmits these rays out of the upper component lens in a direction parallel to the common axis.
