28mm Short Working Distance, LF Series Fixed Focal Length Lens

Product Details Note: 28mm focal length does not work on all F-mount cameras. Camera F-mount must have an inner diameter greater than 42mm. Full Frame (35mm), F-Mount Lens 29 MegaPixels, 5µm Pixel Size Sensors F-Mount Large Format (LF) Lens for Factory Automation 28mm to 100mm Focal Length TECHSPEC LF Series Fixed Focal Length Lenses are designed for use with 2k, 4k, 6k, and 8k line scan cameras and mid-sized area scan arrays. Optimized for machine vision working distances, LF Series lenses feature high resolving powers to easily detect small defects. Additionally, these lenses also feature a lockable focus and iris, which is ideal for factory automation applications where vibrations can cause performance decreases. TECHSPEC LF Series Fixed Focal Length Lenses are ideal for use in machine vision, web inspection, sorting, and identification applications. The lenses come in focal lengths ranging from 28 to 100mm. Note: 28mm focal length does not work on all F-mount cameras. Camera F-mount must have an inner diameter greater than 42mm.
