Kowa LM-LF / LM-CLS
Large Format, Line Scan F-Mount / TFL-II Lenses

Kowa LF high-resolution large-format machine vision lenses are engineered for rigorous industrial imaging. With a 46.0mm image circle, these optics are optimized for 4K line scan cameras and large-sensor area scan systems. They accommodate pixel sizes starting at 7.5µm. These line scan lenses provide exceptional edge-to-edge sharpness and minimal distortion, ensuring precise image capture even during close-range inspections. They are specifically suited for the detailed examination of large objects, including textiles, PCBs, and various industrial components.

By combining a broad image circle with high measurement accuracy, LF lenses support critical applications in factory automation, metrology, electronics manufacturing, and semiconductor inspection. These precision optics deliver the reliable clarity necessary for demanding high-quality inspection tasks.

  • For sensors with pixel sizes from 7.5µm on LF line scan models and 3.1µm on CLS color line scan models.
  • Designed for large-format line scan cameras.
  • Large image circle options up to approximately 43.3mm to 46mm depending on model.
  • Available with Nikon F-mount or TFL-II mount options.
  • Optimized for 4K line scan cameras.
  • Very low distortion for web, print, packaging and materials inspection.
  • Manual focus and iris control.
  • Multiple focal lengths available for different working distances and fields of view.
