4-4 Senarmont Compensator (U-CSE)

Measuring

} Always use interference filter (IF 546 or IF 550). If interference filter is not used,

measurement will not be possible.

# Due to its high detection sensitivity, use of the IF546 interference filter is recommended.

Adjusting of Analyzer Angle

# Perform the following adjustment with no specimen positioned on the stage.

1. Insert the U-CSE into the test plate adapter (U-TAD) or polarization attachment (U-PA) as far as it will go.

2. Fine adjust the polarizer of the condenser (U-POC) to obtain complete extinction.

3. Then fine adjust the rotatable analyzer (U-AN360P) to obtain complete extinction.

4. Repeat the steps 2 and 3 about 3 to 5 times.

5. At this point, read the analyzer's final angle. → θ
