Abstract
This invention provides for a magnification system (10) and a method of construction. The magnification system (10) includes at least a first lens (3) and a second lens (5) lying on a common central lens axis line with an object (1) to be magnified being placed on one side of both of the first lens (3) and the second lens (5). The first lens (3) is constructed in a manner to have a first lens focal length greater than the first lens object distance for forming a first lens virtual image (4). The second lens (5) has a second lens focal length which is greater than the focal length of the first lens (3) to form a second lens virtual image (7) having a greater magnitude than the first lens virtual image formed. Through a recursive image nesting method, additional lens groupings may be added to a basic lens set to increase the magnification while minimizing optical distortions of a previous lens grouping.
