This 18mm fixed focal M12 machine vision lens is optimized for 1\/2\u201d image format 3MP CMOS\/CCD sensors, engineered with ultra-low <0.1% distortion optical structure and fixed F10 aperture to deliver consistent, distortion-free imaging for precision industrial machine vision and compact industrial inspection equipment. As a professional low distortion M12 industrial lens, it balances compact dimensional design and stable optical performance, resolving blurring and geometric deformation pain points of ordinary general-purpose CCTV lenses in high-precision measurement scenarios, widely adopted across automated production inspection, compact equipment visual positioning and miniature industrial monitoring fields. Core optimized keywords: M12 machine vision lens, low distortion industrial fixed focal lens, 1\/2 inch 18mm M12 lens.<\/p>\n
Field of View\/Focal Length Advantages<\/strong><\/p>\n Custom-calibrated 25\u00b0 diagonal \/20\u00b0 horizontal \/15\u00b0 vertical fixed FOV with 18mm focal length, eliminates repeated FOV adjustment work for small-space precision detection, different from wide-angle distorted or ultra-narrow telephoto incompatible alternative lenses.<\/p>\n Performance<\/strong><\/p>\n Ultra-low distortion<0.1% paired with fixed F10 constant aperture, avoids light fluctuation-induced imaging instability common in variable iris lenses, guarantees uniform picture sharpness across full image sensor for 3MP pixel output.<\/p>\n Compatibility<\/strong><\/p>\n Standard M12\u00d70.5 mount plus \u03a614\u00d717.1mm mini dimension, directly fits all mainstream M12 interface industrial cameras matching 1\/2\u201d sensor size without extra structural modification.<\/p>\n Quality Assurance<\/strong><\/p>\n Strict full-lens optical batch testing + compact all-metal lens housing, stable T.T.L 32.5mm mechanical size prevents dimensional deformation under long-time industrial ambient temperature changes.<\/p>\n This product is RoHS certified, ISO9001 quality control certified, supports third-party testing, and complies with EU\/domestic security equipment access standards, alleviating customer quality concerns.<\/p><\/blockquote>\n Core Application Scenarios<\/strong><\/p>\n Primarily deployed in miniature automated production line dimensional inspection, small electronic component appearance defect detection, compact AGV robot visual positioning, miniature industrial equipment built-in monitoring, compact automated sorting machine vision collection, precision parts size measurement equipment, mini intelligent warehousing pickup identification modules, compact laboratory optical detection instruments, small automated assembly machine visual alignment, miniature intelligent logistics barcode scanning cameras, tiny equipment built-in safety monitoring and compact industrial IoT visual collection terminals. Thanks to ultra-low distortion below 0.1%, it meets high-precision measurement demands unavailable for conventional ordinary CCTV lenses; compact \u03a614\u00d717.1mm outer size perfectly fits narrow internal installation space of mini industrial equipment, no customized lens housing transformation needed to cut customer mechanical modification cost, fixed F10 aperture ensures stable imaging under consistent indoor factory ambient lighting for uninterrupted round-the-clock industrial inspection work.<\/p>\n Compatible Devices List<\/strong><\/p>\n Compatible with all mainstream 1\/2-inch 3MP CMOS\/CCD industrial image sensors, perfectly matching miniature M12 interface global industrial machine vision cameras, compact USB industrial inspection cameras, embedded IoT visual acquisition modules, mini automated inspection camera modules, small barcode identification camera assemblies and customized miniature visual detection equipment from mainstream domestic and overseas camera manufacturers. Flexible non-standard focal length and FOV customization service is available to satisfy personalized device matching requirements for special industrial inspection projects.<\/p>\n Designed for industrial machine vision application.<\/p>\n Q1: Can this M12 low distortion lens work with sensor sizes other than 1\/2 inch?<\/strong><\/p>\n A: It is optimized for 1\/2\u201d format; using smaller 1\/3\u201d sensors will narrow actual FOV while maintaining original low distortion performance, larger sensor sizes cause vignetting at image edges.<\/p>\n Q2: Is the fixed F10 aperture adjustable on this fixed focal machine vision lens?<\/strong><\/p>\n A: This lens adopts fixed iris structure with unchangeable F10 aperture, designed to maintain consistent luminous flux for long-running precision industrial detection.<\/p>\n Q3: What\u2019s the shortest working distance this low distortion industrial lens supports?<\/strong><\/p>\n A: The minimal object distance is fixed at 0.2m; objects closer than 20cm cannot achieve clear focused imaging.<\/p>\n Q4: Does this lens support outdoor high-temperature industrial environment use?<\/strong><\/p>\n A: Standard version is for indoor factory environment; customized high-temperature resistant coating version can be produced upon customer requests.<\/p>\n <\/p>\nDownload Specs Sheet<\/a>\n <\/p>\n <\/p>\n\n <\/p> Detailed Product Parameter<\/h2>\n
