AT 020/AT 030 Applanation Tonometer
This instrument for intraocular pressure measurement easily mounts to
the microscope body. It is moved into the operating position by
swinging its measuring arm down.
The operation of this instrument is described in a separate manual for
AT 020 or AT 030. Observe the manuals of these instruments.
Beam splitter
The beam splitter is inserted in the observation path between magnifica-
tion changer and convergent or parallel tube. It is mounted by means
of annular dovetail mounts and hexagon head screw (1, Fig. 9). The
beam splitter is required for the use of further accessories for
documentation and co-observation (TV adapter, camera attachment,
co-observation tube).
With push-pull rod (2, Fig. 9) a prism slide is moved to send either
100 % of light to the binocular tube (rod pushed in) or divide it into
50 % each to binocular tube and accessory attachments (rod pulled
out).
TV-Compact Camera 020
As the beam splitter, the Compact Camera 020 is mounted between
microscope body and tube.
The TV-Compact Camera delivers a video signal. For this, 50 % of the
light energy of the right-hand light path are used. This, however, will
not affect viewing through the eyepiece.
Filter changer with barrier filter (yellow)
The filter serves as barrier filter for the work with fluorescein and with a
blue filter in the observation path. You can swing the yellow filter into
the light path by means of the lever shown beside. In the drawn
position of the filter control lever, the filter is not in the light path.
Special eyepieces
12.5x eyepieces and a 10x micrometer eyepiece with linear and angular
scales are available.
