Description

Price includes shipping.

The CaliBall II is used in horizontal interferometer set ups and is held in a Zygo type 4” bayonet mount that provides the adjustments to align the CaliBall II to the transmission sphere. 

Details of the CaliBall™ II package:

  • The CaliBall™ II comes with all the same components as CaliBall™ I but it is better suited for use with horizontal looking interferometers that are equipped with a Zygo style 4” bayonet mount with x-y-z adjustments
  • CaliBall™ II does not need a separate x-y-z mount because the bayonet mount performs this function

The Random Ball Test* has been reviewed in papers by authors at both NIST and CSIRO who conclude they are not aware of a better method of transmission sphere calibration. 
(See papers about the Random Ball Test under Technical Papers)

*The Random Ball Test is not reliable for calibrating transmission spheres slower than about f/7.

  • The PSM is an ideal tool for finding the center of curvature of a ball or the axis of a cylinder. The question is for how small a ball or cylinder can the PSM do this?

    The smallest article that was readily available was a piece of monofilament 8 pound test fishing line that was 290 μm in diameter. There was no problem finding the axis of the fishline, and separating the Cat’s eye reflection from the surface from the confocal reflection of the axis. The experiment was done with a 5x objective, and the result would have been even more definitive using a 10x objective.
