      Article Summary

      NOTE
      When modifying the sensor sensitivity the PRNU and DSNU reference data become invalid. 
      1. Deactivate DSNU and PRNU references.
      2. Create new data sets for shading and black reference.

      Low speed of the inspected object and good illumination

      1. In the Configuration window navigate to Camera Image Calibration → Sensitivity.
      2. Below Camera sensitivity gain select a low sensitivity gain:
        Achieve the highest dynamic range for areas with high contrast (completely dark to absolutely reflective).
        → E.g. pin inspection in electrical connectors.

      High speed of the inspected flat object and bad illumination

      1. In the Configuration window navigate to Camera Image Calibration → Sensitivity.
      2. Below Camera sensitivity gain select a high sensitivity gain:
        Achieve a good image quality for flat objects.
        → E.g. solar cell, web or wafer inspection.
