It measures 1 inch in diameter and fits directly into the eyepiece or stage of compatible optical comparators. This type of reticle overlays a precision reference grid or measurement scale onto the magnified image, allowing machinists, quality control inspectors, and metrologists to perform accurate dimensional inspection of small parts. It is a standard consumable tool in any metrology-equipped shop or inspection department.\u003c\/p\u003e\n\u003cp\u003eThis chart and reticle is suited for dimensional inspection tasks in manufacturing, toolroom, and quality assurance environments. It is used wherever fine part features must be verified against a known reference scale at 7x magnification. Typical applications include thread form inspection, radius verification, and profile comparison on machined or stamped components. It is installed and used by machinists, QC technicians, and metrologists working with bench-mounted optical comparators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 7x magnification optical comparator systems\u003c\/li\u003e\n  \u003cli\u003e1 inch overall diameter fits standard comparator eyepiece or stage mounts\u003c\/li\u003e\n  \u003cli\u003eProvides a reference overlay for dimensional and profile inspection\u003c\/li\u003e\n  \u003cli\u003eCompact single-piece format for straightforward installation and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement reticle for optical comparators accepting a 1 inch diameter chart and reticle at 7x magnification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eReticle installation is typically performed by a machinist or metrology technician. Power down and secure the comparator before handling optical components. Handle the reticle by its edges only to avoid contaminating the optical surface. Consult the comparator manufacturer's service documentation for proper seating and alignment procedures specific to your instrument.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Magnification\u003c\/strong\u003e: 7x\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40-081-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714551808306,"sku":"40-081-2","price":22.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40cbd19de626390d54781461042d2768.jpg?v=1788503096","url":"https:\/\/voomisupply.com\/products\/spi-40-081-2-optical-comparator-chart-reticle-1-in-7x","provider":"Voomi Supply","version":"1.0","type":"link"}
