Meiji Microscope Auxiliary & Protective Lenses

Auxiliary Lenses are used to increase the working distance of your microscope so you have room for your hands and your tools while using a microscope.  While they reduce the top magnification of your scope they have the double benefit of increasing the field of view while giving you more room to manipulate tools.  These are good things when doing stone setting and engraving!   You will not miss the high end magnification as almost all work is done at the lower end of a microscopes magnification range. If you do need the high magnification simply remove the auxiliary lens.
