ICT/P polarizer
Attached with the knurled screw on the left (6.1),
the pin at the right on the underside of the
condenser holder serves as a stop when the
polarizer is swung in and out. Slot (6.3) is only for
λ
- or
λ
/4 compensator (32.5), not filters!
Intermediate piece with filter mounts
Only in combination with lamphousing (series
105/106/107): The intermediate piece* with filter
mounts (Fig. 21) taking 2 filters with Ø 50 mm can
be additionally assembled between the stand
and the lamphousing.
7 different condenser types are available for
this microscope series (Figs. 7 – 13). Further

p. 32.
Condensers CL/PH and CLP/PH and UCL/UCLP
For polarization the strain-free Pol versions CL P /
PH 0. 85 or UCLP 0. 85 (similar to 7.1 and 7.4) or
the UCA/P condenser (Fig. 10) are necessary.
The full name of the condenser has the suffix
S1. This signifies that the condenser is intended
for use with specimen slides of ca. 1 mm
thickness. To be more precise (as per DIN/ISO)
1.0 to 1.2 mm

table on p. 32.
If the condenser is not yet complete, the
following components* may have to be fitted
before the condenser is adapted to the
microscope (Fig. 14), see p. 16 for fitting details.
Auxiliary condenser lens LS
The auxiliary lens LS (8.1, for DM LS microscope
only) must not be inserted at the bottom of the
condenser, or it will not be possible to obtain
exact Koehler illumination,

Condenser disc UCL*
Condenser discs* (9; 11) can be inserted into
condensers UCL 0.90/1.25 OIL (7.1), UCLP 0.85
and UCA/P (10.5) for certain illumination
techniques (darkfield = DF, phase contrast = PH,
polarization = whole- and quarter-wave
compensator) and the lens for objective 2.5x.

p. 14.
To remove and assemble the disc, screw out the
screw (7.2; 9.4; 11.9) completely. Turn back the
centering screws (9.3) with the centering keys
(7.5) until the light rings, whole- and quarter-
wave compensator* and lens* 2.5x (Fig. 9) can
be inserted.
Light rings*
The largest hole is for brightfield observation
(= BF), the smaller ones for light rings or whole-/
quarter-wave compensators. If you use a
smaller hole for brightfield, the maximum
illumination aperture cannot be used.
