2 MegaPixel Fixed Focal Length Lenses are designed for machine vision applications that require higher resolution than the MegaPixel Fixed Focal Length Lenses. These C-Mount lenses feature built-in locking mechanisms for the manual focus and iris, preventing unwanted adjustments. Lenses with a fixed focal length from 4 to 50mm are available with the 6 to 50mm lenses featuring M30.5 x 0.5 filter thread, allowing the use of machine vision filters. 2 MegaPixel Fixed Focal Length Lenses cover ½” and 2/3” sensor sizes, making them compatible with all of our 2MP machine vision cameras. These lenses are used in industrial machine vision, factory automation, and factory inspection applications.
