Swing in 10x objective in the light path. Adjust the condenser aper-
ture diaphragm. Retrieve the two centering keys (Ref Fig 13 Part 5)
and insert them in the centering holes (Ref Fig 10 Part 1) above the
objective you want to center. Focus the POL sample.
i) Bring some prominent point of the specimen to the center of the
Eye Piece crossline (Fig 24 (a)).
ii)Loosen the stage locking thumb screw which will allow the Round
Stage to rotate 360 degree horizontally. Rotate the round stage
360 degree until the prominent point of the specimen is furthest
away from the center of the Eye Piece crossline, it may even be
outside the field of view. (Fig24 (b)).
iii) Adjust the image with the centering screws over the objective
until the prominent point of the specimen is midway between the
center of the Eye Piece crossline. (Fig 24 (c)).
iv) Adjust the specimen so that the prominent point is at the center
of the Eye Piece crossline. (Fig 24 (d)) Check that it stays at the
center of the Eye Piece crossline when the stage is rotated 360
degree. Repeat the centering process if necessary.
Note: Each objective must be centered separately.
