It measures 1 inch in overall diameter and provides graduated increments of 0.005 inches, allowing technicians and quality control professionals to make precise dimensional measurements and part profile comparisons. This reticle is placed in the optical path of a comparator to overlay a scaled reference grid directly onto the magnified image of the workpiece. Machinists, toolmakers, and metrology technicians use this type of reticle for inspection of part geometry, thread profiles, and edge contours.\u003c\/p\u003e\u003cp\u003eThis chart and reticle is suited for use in shop-floor and laboratory optical comparator setups requiring 7x magnification. It is commonly used in manufacturing environments where repeatable, non-contact dimensional inspection is required. Applications include verification of small machined parts, stamped components, cutting tool profiles, and other precision workpieces where visual overlay measurement is the preferred inspection method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch overall diameter fits standard comparator reticle holders for 7x magnification systems\u003c\/li\u003e\n\u003cli\u003e0.005 inch graduation increments for fine-resolution dimensional overlay measurement\u003c\/li\u003e\n\u003cli\u003eOptical-quality construction for clear, distortion-free reticle imaging\u003c\/li\u003e\n\u003cli\u003eNon-contact inspection method reduces risk of part damage during measurement\u003c\/li\u003e\n\u003cli\u003eCompact single-unit package suitable for bench or toolroom use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with optical comparators operating at 7x magnification that accept a 1 inch diameter reticle insert.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified metrology technician or machinist familiar with optical comparator operation. Power down or disable the comparator light source before inserting or removing the reticle to avoid eye exposure to the projection lamp. Handle the reticle by its edges only to prevent smudging the optical surface. Consult the comparator manufacturer's documentation for proper reticle seating and alignment procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Increments\u003c\/strong\u003e: 0.005 inches\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 40-093-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51708099395890,"sku":"40-093-7","price":22.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31370742ecbb0c5a50a314ad592cb4a7.jpg?v=1788444167","url":"https:\/\/voomisupply.com\/products\/spi-40-093-7-optical-comparator-chart-reticle-1in-7x","provider":"Voomi Supply","version":"1.0","type":"link"}
