Scenario-Based Functional Descriptions<\/h2>\n

100\u00b0\u201331\u00b0 Varifocal Wide-Angle Coverage, Flexible Framing<\/strong><\/p>\n

With a horizontal FOV spanning 100\u00b0 down to 31\u00b0, this Wide Angle Lens adapts seamlessly to diverse monitoring needs. In outdoor security deployments\u2014core use cases for CCTV Lens\u2014or industrial inspection lines, the adjustable zoom lets users switch between wide-area overview and detailed close-ups, eliminating blind spots and boosting accuracy for Machine Vision Lens analytics.<\/p>\n

F1.6 Aperture for Crisp Low-Light Day & Night Vision<\/strong><\/p>\n

The fast F1.6 aperture captures far more light than standard F2.0 lenses. Paired with dedicated IR correction, this IR Corrected Lens produces sharp, low-noise 2MP imagery in dim warehouses, parking areas, and nighttime roadways. This makes it a reliable Varifocal Day&Night Lens for 24\/7 security and a robust ITS Lens for traffic monitoring after dark.<\/p>\n

Manual Control for Industrial & CCTV Precision<\/strong><\/p>\n

Full manual adjustment of iris, focus, and zoom ensures stable, repeatable performance in fixed installations. As a versatile Zoom Lens designed for durability, it excels in factory automation as an FA lens and industrial setting as an Industrial Lens, delivering consistent imaging for quality inspection and process monitoring.<\/p>\n

0.1m M.O.D. for Close-Up Industrial Detection<\/strong><\/p>\n

With a minimum object distance of 0.1m, this C-Mount Lens excels at short-range machine vision tasks. Its compact industrial build integrates easily into embedded vision systems, making it a practical Machine Vision Lens for component verification, barcode reading, and precision positioning in FA and industrial environments.<\/p>\n
