The i72 Angle reference standard is now available to all Laser Interferometer and Autocollimator manufacturers, calibration laboratories, and rotary axis OEM’s

The i72 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. Capable of fully automated calibration resulting in significant time savings over more traditional methods.

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.

As the original manufacturer of these units RPI can also offer a comprehensive repair and calibration service to all existing units.
