Caution when mounting
Two ¢45 filters (each should be less than 3mm in thickness) can be
set on the diffuser holder. Place the filter on the diffuser holder and
insert the holder into the base as shown in Fig. 23-2. (Since filters
are not securely fixed on the holder, do not turn the holder
upside-down while mounting.)

1 6. Objectives and Eyepieces
In the LABOPHOT2-POL, the CF P objectives (strain-free) and CF
eyepieces based on the CF (Chromatic Aberration Free) system are
adopted. Always use the CF objective and the CF eyepiece in
combination.
Since the compensation of chromatic aberration is carried out
respectively in the objective and the eyepiece, the direct image produced
by the objective can be utilized for observation by a TV camera, etc.
- With the objectives marked" 1 60/0.1
T,
use a coverglass of O. 17mm
in thickness.
-The indication" 160/-" on the objective means that no matter whether
a coverglass is used
CJr
not, no decrease of image definition or of
contrast will result.
-When the eyepiece with cross lines and scale is Inserted into the
eyepiece sleeve with the orientation pin fitted to the right-hand groove
of the sleeve, the O-direction of the analyzer and dia-polarizer are
aligned with the cross lines direction.
If the orientation pin is fitted to the upper-right groove of the sleeve,
the cross lines will be aligned with the diagonal position of the
polarization.
- CF PL Projection lenses are exclusively designed for photomicro-
graphy. Do not use them for observation.
- For focusing with the binocular observation tube in photomicrography,
use the eyepiece with photo mask.
