Because the EMZ-8TR uses different optics than the standard EMZ-8, it requires its own auxiliary lens — the MA794 is not interchangeable with lenses intended for other Meiji heads.\u003c\/p\u003e\u003cp\u003eThe .5X is the most popular auxiliary lens choice for this microscope, and it's easy to see why. By adding the MA794, you extend the working distance from \u003cstrong\u003e104mm to 174mm\u003c\/strong\u003e, creating generous clearance for hands, tools, and workpieces beneath the objective — a significant advantage when performing detailed jewelry repair, stone setting, or precision metalwork.\u003c\/p\u003e\u003cp\u003eThe trade-off is a reduction in maximum magnification: with 10x eyepieces, the upper limit drops from 45x to \u003cstrong\u003e22.5x\u003c\/strong\u003e. For most jewelry and bench work, this is not a limitation — the majority of tasks are performed at lower magnifications where the added working room provides a clear practical benefit.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned exclusively for the Meiji EMZ-8TR Trinoc Microscope Head\u003c\/li\u003e\n\u003cli\u003eExtends working distance from 104mm to 174mm for increased hand and tool clearance\u003c\/li\u003e\n\u003cli\u003eMost popular auxiliary lens option for the EMZ-8TR\u003c\/li\u003e\n\u003cli\u003eReduces maximum magnification from 45x to 22.5x when used with 10x eyepieces\u003c\/li\u003e\n\u003cli\u003eIdeal for jewelry, stone setting, and detailed bench applications where working distance is critical\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMagnification\u003c\/th\u003e\n\u003ctd\u003e.5X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Microscope Head\u003c\/th\u003e\n\u003ctd\u003eMeiji EMZ-8TR Trinoc Microscope Head\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking Distance (without lens)\u003c\/th\u003e\n\u003ctd\u003e104mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking Distance (with lens)\u003c\/th\u003e\n\u003ctd\u003e174mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Magnification (with 10x eyepieces)\u003c\/th\u003e\n\u003ctd\u003e22.5x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard Maximum Magnification (with 10x eyepieces)\u003c\/th\u003e\n\u003ctd\u003e45x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eThe EMZ-8TR requires a different auxiliary lens than the standard EMZ-8.
