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.
