{"product_id":"leica-a60f-0-50x-auxiliary-lens","title":"Leica A60F 0.50x Auxiliary Lens","description":"\u003cp\u003eNeed more working distance for your Leica A60F microscope? The standard Leica A60F provides a working distance of 122 mm (4.8\") between the lens and focal point, which many users find adequate. However, jewelers and metalsmiths who require greater clearance beneath the lens — for larger workpieces, additional tools, or more comfortable hand positioning — will benefit from adding this 0.50x auxiliary lens.\u003c\/p\u003e\n\n\u003cp\u003eAdding this auxiliary lens increases working distance from 122 mm (4.8\") to approximately 200 mm (7.8\"), giving you significantly more room to maneuver. The trade-off is a reduction in magnification range, from the standard 5x–30x down to 2.5x–15x. Field of view increases correspondingly, from the standard 46 mm–7.5 mm to 90 mm–15 mm. Most jewelry work performed under a microscope is done at lower magnifications, so the reduced upper magnification limit rarely affects day-to-day use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePlease note: This lens requires the Leica A60 objective lens adapter, part number 103.727, sold separately.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIncreases working distance from 122 mm (4.8\") to approximately 200 mm (7.8\")\u003c\/li\u003e\n\u003cli\u003eExpands field of view from 46 mm–7.5 mm to 90 mm–15 mm\u003c\/li\u003e\n\u003cli\u003eReduces magnification by a factor of 0.50x, yielding a zoom range of 2.5x–15x\u003c\/li\u003e\n\u003cli\u003eIdeal for jewelers and metalsmiths who work with larger pieces or require additional hand clearance\u003c\/li\u003e\n\u003cli\u003eCompatible with the Leica A60F microscope when used with the required objective lens adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAuxiliary Lens Factor\u003c\/th\u003e\n\u003ctd\u003e0.50x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eZoom Range (with auxiliary lens)\u003c\/th\u003e\n\u003ctd\u003e2.5x – 15x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking Distance (with auxiliary lens)\u003c\/th\u003e\n\u003ctd\u003eapproximately 200 mm (7.8\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eField of View (with auxiliary lens)\u003c\/th\u003e\n\u003ctd\u003e90 mm – 15 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard Working Distance (without)\u003c\/th\u003e\n\u003ctd\u003e122 mm (4.8\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard Zoom Range (without)\u003c\/th\u003e\n\u003ctd\u003e5x – 30x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard Field of View (without)\u003c\/th\u003e\n\u003ctd\u003e46 mm – 7.5 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 #103.727 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe Leica A60 objective lens adapter (part #103.727) is required for installation and is \u003cem\u003enot\u003c\/em\u003e included with this lens.\u003c\/li\u003e\n\u003cli\u003eAdding this auxiliary lens decreases magnification by the factor of the lens (0.50x).
