Objective Centration (cont.)
5.Adjust the objective centering screws until the noticeable point of the sample is midway between the furthest position and the center of the crosslines. This moves the objective center closer to the stage center.
6.Move the specimen (not the objective centering screws!) so that the noticeable point is at the center of the crosslines once again.
7.Check to make sure that the noticeable point stays at the center of the crosslines when the stage is rotated. If not, repeat the centering process.
Each objective must be centered sepa- 
rately. Also, there is a magnetic storage location for the objective centering tools in the back of the Analyzer or Analyzer/Bertrand Lens
modules.
