{"product_id":"leica-a60f-0-75x-auxiliary-lens","title":"Leica A60F 0.75x Auxiliary Lens","description":"\u003cp\u003eGain greater working distance under your Leica A60F microscope with this 0.75x auxiliary lens. While the standard Leica A60F delivers a working distance of 122 mm (4.8\") between lens and focal point, this auxiliary lens extends that distance to approximately 130 mm (5.1\") — giving your hands and tools more room to maneuver during detailed work.\u003c\/p\u003e\u003cp\u003eAdding the auxiliary lens reduces the magnification factor by 0.75, bringing the zoom range from the standard 5X–30X down to 3.75X–22.5X. The trade-off is a noticeably wider field of view: 60 mm–10 mm versus the standard 46 mm–7.5 mm. For most jewelry work performed under a microscope, lower magnifications are used the majority of the time, making the reduced upper magnification a minimal concern in practice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote: This auxiliary lens requires the Leica A60 objective lens adapter, part number 103.727, sold separately.\u003c\/strong\u003e\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIncreases working distance from 122 mm (4.8\") to approximately 130 mm (5.1\")\u003c\/li\u003e\n\u003cli\u003eWider field of view — 60 mm–10 mm compared to the standard 46 mm–7.5 mm\u003c\/li\u003e\n\u003cli\u003eReduces magnification by a factor of 0.75 for a zoom range of 3.75X–22.5X\u003c\/li\u003e\n\u003cli\u003eProvides additional hand and tool clearance for detailed bench work\u003c\/li\u003e\n\u003cli\u003eCompatible with the Leica A60F microscope when used with the required adapter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAuxiliary Lens Factor\u003c\/th\u003e\n\u003ctd\u003e0.75x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking Distance\u003c\/th\u003e\n\u003ctd\u003e130 mm (5.1\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eZoom Range\u003c\/th\u003e\n\u003ctd\u003e3.75X – 22.5X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eField of View\u003c\/th\u003e\n\u003ctd\u003e60 mm – 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Microscope\u003c\/th\u003e\n\u003ctd\u003eLeica A60F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRequired Adapter\u003c\/th\u003e\n\u003ctd\u003eLeica A60 Objective Lens Adapter, part number 103.727 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe required Leica A60 objective lens adapter (part number 103.727) is not included and must be ordered separately.\u003c\/li\u003e\n\u003cli\u003eAdding an auxiliary lens decreases magnification by the factor of the lens — in this case, 0.75x.\u003c\/li\u003e\n\u003cli\u003eMost jewelry tasks performed under a microscope use lower magnifications, so the reduction in maximum magnification is rarely a limitation in practice.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Leica","offers":[{"title":"Default Title","offer_id":43583417352406,"sku":"103.875","price":320.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/leica-a60f-0-75x-auxiliary-lens-otto-frei.jpg?v=1719956664","url":"https:\/\/www.ottofrei.com\/ja\/products\/leica-a60f-0-75x-auxiliary-lens","provider":"Otto Frei","version":"1.0","type":"link"}
