MC4K series

Macro lenses for 4k linescan cameras Download catalog

MC4K series is a collection of macro lenses fitting both 4K linescan cameras and matrix detector cameras over 4/3″.

These lenses are specifically designed to naturally work as macros, as opposed to infinite conjugate lenses with added spacers: a common alternative but unable to deliver the same optical performances.

MC4K lenses feature a fixed aperture, selected to ensure optimal field depth, image resolution and brightness for each magnification range, while meeting the typical needs of machine vision applications. The absence of an iris adjustment mechanism leads to a simpler and streamlined build, granting extra durability and precision.

Machine integration is made easy thanks to the precise focusing mechanism and the possibility to choose from an F or M42x1 mount (-N). MC4K series additionally features a front M30.5x0.5 thread for insertion of an optional filter as well as easy phase adjustment.

Key advantages

  • Macro design
    Achieve unmatched resolution in critical applications: these objectives consistently deliver superior image quality than standard fixed focal length lenses used with extension tubes.
  • Exceptional low distortion
    Perform measurement tasks with a high degree of accuracy and reliability.
  • Optimized aperture
    For each magnification, the f/# is optimized to ensure the best field depth and image resolution.
  • Easy front filter insertion
    Thanks to the front M30.5x0.5 thread

Notes

  1. Maximum and minimum magnification changes when focusing.
  2. F/# = F-number, wF/# = working F-number, the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request.
  3. Percent deviation of the real image compared to an ideal, undistorted image: typical (average production) values and maximum (guaranteed) values are listed.
  4. At the borders of the field depth the image can be still used for measurement but to get a perfectly sharp image only half of the nominal field depth should be taken into account.
  5. Measured from the front end of the mechanics to the camera flange; take into account a +/- 2.5 mm tolerance due to the focussing mechanism.

Ordering information

Part numbers are coded as MC4KyyyX -x where yyy refers to the magnification and -x refers to the mount option:
-F for F-mount
-N for M42x1 mount (flange distance FD 10.56 mm).
For example, MC4K100X-N defines a MC4K100X with M42x1 mount.

Mount options

MC4K can be ordered with standard F mount or M42x1 (identifiable by the -N suffix).

Mount F

Mount N = M42x1

Phase adjustment

Adjusting the phase of the camera is easy: simply loosen the three set screws and rotate the camera mount until you achieve the desired angular alignment.
