Note on Measuring:

} Measuring is usually performed with the condenser's top-lens swung out and the aperture iris

diaphragm stopped down. If it is required to maintain brightness and resolution, the top-lens should

be left engaged although measuring accuracy will decrease.

} When measuring retardation, backlash error may occur when the compensator knob is rotated (U-CBE,

U-CTB, U-CBR1, U-CBR2). Accordingly, keep the rotation direction always uniform. If the knob is rotated

too far, turn it fully back and restart rotation by keeping the direction uniform till the measured portion.

Adjusting the Extinction

Perform the cross-Nikol adjustment and the eyepiece cross

line alignment as described in the instruction manual for the

polarizing microscope (BX53/BX53M-P or CX31-P).
