Product Family Description

  • Up to 174mm Image Circle for Line Scan or Area Scan
  • C-Mount, F-Mount, T-Mount Lens
  • Up to 1.3 MegaPixels or 8k Line Scan, 7µm Pixel Size Sensors
  • 35mm to 135mm Focal Length

Originally designed as enlarging lenses, these high-resolution lenses can accommodate 1" format sensors and larger, which makes them a great choice for line scan cameras. This unmatched adaptability, combined with low distortion and constant resolution over the entire viewable field, makes Rodagon lenses optimal for close focus applications for which they consistently yield higher magnifications and better resolution than standard fixed focal length lenses. This makes them ideal for use with high-resolution cameras.

Lenses have M39 x 1/26" base threading. A Leica Lens Adapter (#14-705 for the 35, 50, 60, 80, and 105mm lenses or #54-126 for the 135mm lens) is required and sold separately to allow attachment to the Modular Focus Tube (MFT). The MFT is required for focusing the lens and for connection to standard camera mounts. The MFT does not ship with a camera adapter; camera adapters for C-Mount, F-Mount, T-Mount (M42 x 0.75), SLR-mount (M42 x1.0), and M72 x 0.75 are available and sold separately. For closer working distances, additional extension tubes can be added (see "Working With Spacers" specification table); values should be used for reference only; choose #57-791 for M72 cameras and #56-965 for all others.

Note: See Technical Image section for spacer length.

Rodagon Modular Focus Tube (#14-707) and Camera Adapters

To use with a camera, attach a C-Mount, F-Mount, T-Mount, SLR, or M72 adapter (each sold separately) to the Rodagon Modular Focus Tube. Extended range (25mm full stroke) accommodates a range of working distances without requiring spacers. Precision design allows lens to remain centered and unrotatable during focusing. Locking screw included.

Please contact Applications Engineering for assistance in properly configuring this lens for your application.
