ABSTRACT
For a single lens magnifier, this is usually limited to about 4X due to lens aberrations. How then to increase the magnification of an object and retain a good quality image? We use lenses in combination. There are two ways of combining lenses:
When two thin lenses are placed very close together, we say they are “in
contact.” The power of the combination of the lenses is the sum of the powers of each lens.
