OBSERVATION METHODS (Using BX-RLA2)

6-1 Reflected Light Brightfield Observation

See "REFLECTED LIGHT BRIGHTFIELD/DARKFIELD OBSERVATION PROCEDURE" on page 5.

6-2 Reflected Light Nomarski DIC (Differential Interference Contrast) Observation

# The performance of polarizer may deteriorate when it has been exposed to light for a long period (about continu-

ous 2000 hours). If this happens, replace the polarizer.

# When performing sensitive color observation using the U-DICRH DIC slider, combine the U-POTP3 polarizer.

#When using the high-intensity light source, be sure to use the U-25L42 filter to prevent the polarizer from being burnt.

Setting the Analyzer and Polarizer

# In the current step, do not engage the DIC slider in the light path.

1. Bring the specimen in approximate focusing using the 10X or 20X objec-

tive.

2. Remove the cover to enable installation of the U-AN360-3 analyzer. Then

put the analyzer @ in the insertion slot.

3. Insert the U-PO3 or U-POTP3 polarizer ² so that the surface with indica-

tion comes on the front, and engage the polarizer in the light path.

4. Rotate the analyzer rotating dial ³ to find the position where the field of

view is darkest.

}An approximate cross-Nicol position can be obtained by setting the index

on the dial ³ on the outer side. Fine-adjust the dial by rotating it near this

position to find the position where the field of view is darkest.
