Considerations about accuracy
 
OPTOMATIC has been designed to cover a large measuring range and in this way to become a universal measuring tool. To enable this without sacrificing the accuracy, OPTOMATIC uses selected hardware components like high resolution CCD array, precision microscope objective or highly corrected achromats in order to accomodate to different samples and different optical parameters.
 
Moreover the software automatically adapts to different requirements when measuring under extreme conditions as too small or very long focal lengths, uncorrected lenses (poor image quality), poor contrast, etc. The software also increases more than 20 times the resolution of the CCD, so that the measurement of the target image is made with a resolution smaller than 1µm.
 
The unavoidable inaccuracies of the system components are eliminated through individual calibration using high precision master lens certified by different national standard institutes. This sofisticated and costly calibration procedure assures the highest absolute accuracy of each instrument. The calibration values are stored in a special file and automatically used to correct the raw measurement data. The displayed measurement results are always corrected by means of calibration values specific to each instrument. The sofisticated calibration procedure is paying off in superior performance as well in increased repeatability. On request Master lens calibrated by national standard institutes are supplied to customers for in-house checking of the calibration of the instrument or to be used when certification according ISO 9000 is equired.
