Troubleshooting

Lens calibration failed: The quick line measurement was significantly off.

OR

Parcentric/parfocal calibration failed: When parcentric/parfocal was tested, the tracing did not remain in the same position between objectives.

 

Try the following:

1. Check the camera alignment.
2. Check the stage movements.

 

Once those have all been examined, perform grid-tuning and parcentric/parfocal calibration again to see if any issues were resolved:

1. Re-calibrate (grid tune) the lenses and test the calibration with the quick measure line (see Calibrate lenses with calibration grids ).
2. Re-calibrate parcentric and parfocal and test the calibration by drawing a contour and switching through the objectives to make sure it stays aligned (see Parcentric/Parfocal calibration ).

 

If, after checking the camera, stage, and Z encoder, the calibration remains unsatisfactory, contact us for additional assistance.
