When using a TCA job template on a system with two cameras (AxioCam 705POL and a color camera, e.g. AxioCam 305c), there might be an offset between those cameras.

Example: Offset between AxioCam 705POL and color camera
Example: Offset between AxioCam 705POL and color camera

You check and correct the camera offset in the Edit View.

Note that you perform the offset correction on one particle and then the stage movement is corrected accordingly to the new coordinates for all particles. This applies only to the currently running job template. If you start the job template once more, you again need to correct the camera offset, because the offset settings are not saved.

  1. You are running a TCA job template in dual camera mode.
  2. You have acquired particle images.
  1. Go to the workflow step Size Distribution (Live), and in the Edit View check whether there is an offset between the two cameras.
  2. Here, you have the option to correct the offset. The Use Offset Correction checkbox is activated by default.
  3. Under Select Camera, select the color camera, and under Offset Correction, press Determine Offset.
  4. The Offset Correction mode is activated. The cursor changes to a cross.
  5. In Live View, click in the center of the particle whose stage coordinates you want to correct.
  6. The stage moves to the particle. The offset in displayed in µ in the Offset Correction control .
  7. If you are not satisfied with the result, click Reset

    and select the same particle again, or choose a more suitable one. Carry out the offset correction again.
  1. You have corrected the camera offset of the color camera. In the Position List with EDF workbench and in the Interactive Height Measurement workbench you can continue with your work with the stage set precisely. The new coordinates are also used here if you activate the color camera.
