The ZMM - 45B has many similarities to the basic ZMM-1 Monocular Zoom Microscope. The principal differences that this unit enjoys is a 45 Degree eye tube versus the straight optical frame. It also offers a longer WORKING DISTANCE, LARGER MAGNIFICATION RANGE AND LARGER FIELD OF VIEW.
It has many uses. In manufacturing wherein these qualities are desirable such as assembly of miniature parts, alignment of Fiber Optic Cables, alignment on wafer slicing machines, and many other miniature electronic applications, checking castings for "Blow Holes", castings for metal structure, or any other application wherein a large range of magnifications in a single unit is helpful with or without the cross hair.
