The Meiji EMZ-10 differs from the Meiji EMZ-5 by having a longer working distance when used without an auxiliary lens 110mm/4-3/8" for EMZ-10 vs 93mm/3-5/8" for the EMZ-5. This increase working distance is 17mm or about 3/4", a relatively small distance. The EMZ-10 is supplied with a protective lens instead of a working distance increasing auxiliary lens that is supplied standard with the EMZ-5 that we sell. You can select from a variety of auxiliary lens that fit both scopes to change the working distance as you see fit. See below for information on auxiliary lenses. Working distance is important to consider in setting up your scope to your working environment. Will you be working on top of your bench or will you set up your bench to work lower near the catch tray? How tall are you? How tall is your bench? How tall is your chair? How much room do you need for your hands and tools? As a general rule, choose an EMZ 10 if you wish to work on-top of your bench. Choose an EMZ-5 if you wish to work lower near your catch tray.

*A word about auxiliary lenses: Auxiliary lenses are used to increase working distances, giving you more space to work between your microscope and your work holding device. Auxiliary lenses increase working distance as they decrease maximum magnification. Since most jewelry work is done at lower magnifications, the loss of the higher powers while using an auxiliary lens is usually not missed. Choosing an auxiliary lens is all about finding a comfortable working position while allowing for adequate space for your tools and work. Many factors need to be considered including scope stand used, bench and chair height, your height and where you position your work holding device; either on top of your bench or closer to the catch tray for example. Use the information below to compare how magnification and working distances change with the various auxiliary lenses available for Meiji microscopes when using standard 10X eyepieces.
