Unlock the holder-moving lever, and move the holder down slowly by the lever.
⑤
Insert the alignment screwdrivers (long, middle, short) into the screw holes of the 5th lens chamber, and
loosen the 3 screws.
⑥
Rotate the micrometers (X and Y), and shift the cross lines by the scales that were results of the chart
shooting of the 5th lens group alignment.
(e.g. Refer to "Pic.2" for the case of <X dire1, Y directions:-1>)
⑦
Fix the 3 screws of the 5th lens chamber with the alignment screwdrivers. Move the holder-moving lever up
to lock the holder.
⑧
Check that a shift length caused by the cross lines and the X/Y lines is equal to the scales (1 = 1 scale of the
calibrated cross lines) of the results of "Chart shooting of the 5th lens group alignment". (ref. Pic.2)
Note: After fixing the 3 screws of the 5th lens chamber, if a shift length is different from the results of the
chart shooting, repeat the procedure from
④
to
⑧
until they become equal.
⑨
Turn each power of the monitor, LINE GENERATOR, and MEGALIGHT 100 to OFF. Remove the lens
from the equipment (for periphery).
Then go back to “(5) Chart shooting of the 5th lens group alignment” and repeat the procedure (5) and (6)
until the result becomes "END".
