Product Family Description

  • 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.

Note: 28mm focal length does not work on all F-mount cameras. Camera F-mount must have an inner diameter greater than 42mm.
