MC4K series is a collection of macro lenses fitting both 4 K linescan cameras and matrix detector cameras over 4/3″. These lenses are specifically designed for macro imaging, as opposed to infinite conjugate lenses with added spacers, a common alternative unable to deliver the same optical performance.

MC4K lenses feature fixed aperture 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 more robust build quality, 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 the 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

Maximum and minimum magnification changes when focusing.
Working distance: distance between the front end of the mechanics and the object. Set this distance within +/- 3% of the nominal value for maximum resolution and minimum distortion.
Working F-number (wF/#): the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request.
Percent deviation of the real image compared to an ideal, undistorted image: typical (average production) values and maximum (guaranteed) values are listed.
At the borders of the field depth the image can be still used fo r measurement but, to get a perfectly sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 7 μm.
Indicates the availability of an integrated camera phase adjustment feature.
Measured from the front end of the mechanics to the camera flang e.

Ordering information

It’s easy to select the right lens for your application: our 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 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.
