Typical linear scales from Heidenhain or Mitutoyo provide a measuring accuracy of about +/- 3μ. For short radii below 50mm this is not accurate enough because this potential inaccuracy can exceed the given radius tolerance of typically 1-3 fringes.
In addition there is a potential error due to the distance of the linear scale to the optical axis of the system.

SRM-Plus is the innovative solution for this problem. A high precise indicator with remote control for zero setting allows the precise measurement of radii up to 60mm (cx and cc) directly in the optical axis of the system with an accuracy of 1μ.
