“Focus” – enabling this option will display a “focus bar graph” in the lower right corner of the VisionMaster Software. In addition, a number is displayed that corresponds to the size (length) of the bar graph.
The higher number (larger the bar graph), the better in focus the video image of a particular surface. Please note that the highest value may vary from sample to sample and can be confused with very dark or very light measurement surfaces. The default setup has this function disabled.
