Self-calibration
Constant precision performance of OPTICOMETER OPT 2000 is ensured by calibration procedure.
The calibration will be done by ‘VISIOPTIMUM’, with CX and CV lenses.
For each calibration, the computer determines : the d axes and the r radius of the rubisballs.
For intermediate values of CX or CV, the computer integrates the d or the r for the inserted value.
This avoids an error that is common on traditional surface meas-urement devices that do not take into consideration the varying measurement relative to different curves, and their contact points between probeball ends.
