The i72 Diamond Standard ^PLUS is a compact high accuracy positioning system for use in the calibration of rotary devices, instrument positioning and other systems where high accuracy and good repeatability are in demand.

The Key Advantages;

• High accuracy and repeatability with +/-0.5 arc seconds of accuracy.
• Capable of fully automated calibration resulting in significant time savings over more traditional methods.
• Fully flexible system capable of operation in 4 orientations including horizontally, vertically or even upside down to cope with all manner of rotary axis applications.
• The 5° indexing capability derived from the extremely high accuracy Hirth coupling design allows 72 positions to be calibrated within 360°. It is virtually impossible to achieve these measurements with an optical polygon.
