Notes:
If you use a smaller hole for brightfield, the
maximum illumination aperture cannot be used.
The lettering (e.g. DF, PH 1 ....., λ) must point
upward, the λ or λ/4 compensators must be
inserted with the correct orientation: The notch
must point towards the center of the disk! The
lettering of the components should
correspond
to
the marking at the opposite position (outer
edge of the disk).
• Tighten the centering screws until the
components are roughly in the center of the
holes
