Fig. 3.5-25    Allowable Angle of Tilt (Type I) with respect to the Z Axis 

(negative angle of tilt) 

 
IMPORTANT:  Set Z and T within the allowable range; otherwise, the specimen may strike the 

objective lens or BSE detector and cause damage to both specimen and them. 

 
 
3.5.6.5    Operating the Z-axis (varying the Working Distance [WD]) 
 
Turning the Z-axis knob, counterclockwise moves the specimen toward the objective lens, and 
reduces the WD.    Conversely, turning the Z-axis knob clockwise moves the specimen away 
from the objective lens, and increases the WD.    The value of the WD can be read off from the 
scale provided on the Z-axis knob. 
Readings from the scale are valid when the combined height of the specimen base on which the 
specimen is loaded and the specimen base stand is set at the Standard position on the height 
gauge.
