14. Retrofitting Components
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 up-
ward, the λ or λ/4 compensators must be in-
serted with the correct orientation: The notch
must point towards the center of the disk! The
lettering of the components should correspond
the marking at the opposite position (outer edge
of the disk).
• Tighten the centering screws until the compo-
nents are roughly in the center of the holes.

Attention:
Before fitting the disk into the condenser, make
sure that neither of the centering screws is
sticking out at the side.
• Fasten the condenser disk with the axis
screw, check that the disk rotates properly
through 360°.
• Affix the condenser with the condenser's
clamping screw.
Condenser UCA/P
• Unscrew the fastening screw of the disk. This
is to be found on the underside of the con-
denser and must be fully screwed out.
• Turn back the centering screws until the light
rings, λ- and λ/4-compensator* and lens* 2.5x
can be inserted.
The largest hole is for brightfield observa-
tion (= BF), the slightly smaller ones for light
rings or λ- and λ/4-compensator or lens*
2.5x.
