This combination of body and lenses delivers the most useful magnification power, field of view, and working distance for the bench jeweler using the GRS Acrobat stand and many other types of adjustable stands in a typical jeweler's bench environment.\u003c\/p\u003e\u003cp\u003eJewelers recognize the outstanding build quality of the Meiji scope and the perfect focus that Meiji optics achieve. The 0.5X auxiliary lens increases working distance so your hands have room to maneuver — a critical advantage when working at the bench. This kit includes the EMZ-5 microscope body (129.405), a pair of Meiji MA502 10X eyepieces with rubber eye guards (129.407), and the Meiji MA517 0.5X auxiliary lens (129.412).\u003c\/p\u003e\u003cp\u003e\u003cem\u003eMicroscope stand and light source sold separately.\u003c\/em\u003e\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eZoom Ratio:\u003c\/strong\u003e 6.5:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZoom Range:\u003c\/strong\u003e 0.7X – 4.5X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZoom Control:\u003c\/strong\u003e Dual, graduated, bilateral mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnification:\u003c\/strong\u003e 7X–45X with 10X eyepieces; 3.5X–22.5X with 10X eyepieces and 0.5X auxiliary lens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField of View:\u003c\/strong\u003e 32mm–5.1mm standard; 65.7mm–10.2mm with 0.5X auxiliary lens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Distance:\u003c\/strong\u003e 93mm standard; 148mm with 0.5X auxiliary lens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEyetube Inclination:\u003c\/strong\u003e 45°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterpupillary Distance:\u003c\/strong\u003e 54mm–75mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDioptric Adjustment:\u003c\/strong\u003e Dual (±5 diopters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Magnification Range:\u003c\/strong\u003e 2.1X–270X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Working Distances:\u003c\/strong\u003e 34mm–251mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eZoom Ratio\u003c\/th\u003e\n\u003ctd\u003e6.5:1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eZoom Range\u003c\/th\u003e\n\u003ctd\u003e0.7X – 4.5X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEyetube Inclination\u003c\/th\u003e\n\u003ctd\u003e45°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInterpupillary Distance\u003c\/th\u003e\n\u003ctd\u003e54mm – 75mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDioptric Adjustment\u003c\/th\u003e\n\u003ctd\u003eDual (±5 diopters)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard Working Distance\u003c\/th\u003e\n\u003ctd\u003e93mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking Distance (0.5X Aux Lens)\u003c\/th\u003e\n\u003ctd\u003e148mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard Magnification (10X Eyepieces)\u003c\/th\u003e\n\u003ctd\u003e7X – 45X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMagnification (10X Eyepieces + 0.5X Aux Lens)\u003c\/th\u003e\n\u003ctd\u003e3.5X – 22.5X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeiji EMZ-5 Stereo Zoom Microscope body — 7X–45X (Part 129.405)\u003c\/li\u003e\n\u003cli\u003eMeiji MA502 pair of 10X eyepieces with rubber eye guards (Part 129.407)\u003c\/li\u003e\n\u003cli\u003eMeiji MA517 0.5X auxiliary lens (Part 129.412)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eA word about auxiliary lenses:\u003c\/strong\u003e Auxiliary lenses increase working distance — an important feature for jewelers working with their hands under a scope — by decreasing magnification power. The 0.5X auxiliary lens is the most common choice for bench-mounted setups using the GRS Acrobat stand, providing a comfortable working environment for jewelers seated at a bench ranging approximately 5'6\" to 6'2\" in height. Depending on your stand, bench and chair height, and personal preference, a different auxiliary lens power may be more suitable. Since most detailed work is performed at lower magnifications, the reduction of higher powers when using an auxiliary lens is generally not a concern. The auxiliary lens can be removed when higher magnification is needed. For prolonged use without an auxiliary lens, the 0X protective lens (129.409B) is available separately.\u003c\/p\u003e\u003cp\u003eThe following auxiliary lens options are available separately and show the resulting working distance, field of view, and magnification with 10X eyepieces:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo lens \/ 0X Protective Lens (129.409B):\u003c\/strong\u003e Working Distance 93mm | Field of View 32mm–5.1mm | Magnification 7X–45X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.3X Auxiliary Lens (129.411):\u003c\/strong\u003e Working Distance 251mm | Field of View 109mm–17mm | Magnification 2.1X–13.5X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.44X Auxiliary Lens (129.410):\u003c\/strong\u003e Working Distance 171mm | Field of View 74.5mm–11.5mm | Magnification 3.08X–19.8X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.5X Auxiliary Lens (129.412):\u003c\/strong\u003e Working Distance 148mm | Field of View 65.7mm–10.2mm | Magnification 3.5X–22.5X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.75X Auxiliary Lens (129.413):\u003c\/strong\u003e Working Distance 97mm | Field of View 43.8mm–6.8mm | Magnification 5.25X–33.75X\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eMicroscope stand and light source are sold separately.\u003c\/p\u003e","brand":"Meiji Techno Microscopes","offers":[{"title":"Default Title","offer_id":43582629839062,"sku":"129.440","price":1719.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/meiji-emz-5-stereo-zoom-microscope-with-10x-eyepieces-and-0-5x-auxiliary-lens-otto-frei.jpg?v=1719956935","url":"https:\/\/www.ottofrei.com\/products\/meiji-emz-5-stereo-zoom-microscope-10x-eyepieces-0-5x-auxiliary-lens","provider":"Otto Frei","version":"1.0","type":"link"}
