Patent ID: 8493655

Claim:
An optical module for increasing magnification of a microscope having an objective and an eyepiece between which is an optical path for light to travel from said objective to said eyepiece, said optical module comprising: (a) light diverging means for dividing said optical path into two parallel light paths after leaving the objective; (b) a plurality of reflective orthonormally-arranged intermediate elements including at least a first and a last reflective element, each reflective element having a reflective surface diagonal relative to orthonormal axes of each of said elements, said axes transverse to said path of said light diverging means, and arranged successively and orthonormally to reflect said light paths, in which each surface diagonal, other than an eye-piece related diagonal, reflect light inwardly toward a next surface diagonal in said parallel light paths from element to element, from said objective when said module is inserted in said optical microscope, beneath said eyepiece, in which none of said reflective elements include a reflective surface parallel to said optical path between the eyepiece and the objective; and (c) means for converging said parallel light paths into a single path before producing an image at said eyepiece.
