Product Family Description

  • Covers Large Format (LF) Sensors up to 43.3mm Diagonal
  • F-Mount Compatible
  • Compatible with 2k – 8k Line Scan Cameras and Mid-Sized Area Scan Arrays
  • Multiple Focal Length Options Available

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.
