Calibration Standards with diffuse reflecting or highly shining
measuring faces. The bases are gauge blocks or measuring
spheres in carbide with scratch resistant surface that also
allows tactile probing. Also available are classical test
pieces like sphere plate with spheres that can be probed
optically or tactile. Coordinate measuring instruments with
optical or tactile measuring probes can be calibrated with
a single standard.
