Manufactured by GRS in the United States, this adapter solves a critical limitation: Leica's own objective lens adapter (part number 129.458) reduces the zoom range from 6:1 to 5:1. The GRS adapter preserves the full 6:1 zoom range standard to the Leica A60, giving professionals the complete magnification performance their microscope was designed to deliver.\u003c\/p\u003e\u003cp\u003eThe Leica A60 was not originally designed to accept objective auxiliary lenses — Leica engineered the A60 to provide satisfactory working distance for most applications without them. However, jewelers working with a wide variety of workholding setups and objects of varying sizes often benefit from extended working distance. Objective auxiliary lenses increase working distance while decreasing magnification, and with this GRS adapter installed, the Leica A60F can accept three different Leica Objective Auxiliary Lenses to achieve different working distances, fields of view, and magnification ranges.\u003c\/p\u003e\u003cp\u003eImportantly, the GRS adapter does not change the working distance of the auxiliary lens used with it compared to using the Leica adapter — the advantage is exclusively the preserved 6:1 zoom range.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePreserves the full 6:1 zoom range of the Leica A60 — Leica's own adapter reduces this to 5:1\u003c\/li\u003e\n\u003cli\u003eCompatible with three Leica Objective Auxiliary Lenses for flexible working distance and magnification options\u003c\/li\u003e\n\u003cli\u003eDoes not alter the working distance of the auxiliary lens relative to the Leica adapter\u003c\/li\u003e\n\u003cli\u003eManufactured by GRS in the United States\u003c\/li\u003e\n\u003cli\u003eAluminum construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e003-727\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Microscope\u003c\/th\u003e\n\u003ctd\u003eLeica A60 \/ A60F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eMade in the USA by GRS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e \u003cem\u003eUnscrew the Leica lens cover that protects the primary lenses.
