3.5.6 Installing a camera
You can install a digital camera, a video camera or
a compact digital camera to your choice on the
microscope via the available camera adapters (see
section 2.1).
•
First, install the phototube (Fig. 32/ 7 ), if
required (see section 3.5.1).
•
Loosen the clamping screw (Fig. 32/ 8 ) and
remove the dust cap from the phototube.
Installing a compact digital camera
•
Sliding mount (Fig. 32/ 4 ), thread adapter ring
M37/52 (Fig. 32/ 3 ) and lens mount (Fig. 32/ 6 )
are supplied pre-assembled as Digital Camera
Adapter P95 M37/52x0.75 . The opposite
drawing shows this unit dismantled.
Furthermore, you may unscrew the M37/52
thread adapter (Fig. 32/
3 ) from the sliding
mount (Fig. 32/ 4 ) (not shown) so that you can
also mount cameras with M37 thread.
•
Mount the adapter ring (Fig. 32/ 2 ) (supplied
with the camera) to the camera (Fig. 32/ 1 ) (see
the operating instructions of the camera).
•
Screw the unit consisting of sliding mount (Fig. 32/ 4 ), thread adapter ring M37/52 (Fig. 32/ 3 ) and lens
mount (Fig. 32/ 6 ) into the adapter ring (Fig. 32/ 2 ).
•
Insert the camera with adapter into the phototube as far as it will go. Align it and fasten it with the
clamping screw (Fig. 32/
8 ).
•
Depending on the microscope equipment or the camera used, it may be necessary to optimize the
distance between camera lens and lens mount (Fig. 32/
6 ) (see double-headed arrow). This will be
necessary in particular, if it is impossible to obtain an unvignetted image in any of the zoom positions
of the camera lens. To this end, adjust the camera as follows:
−
Switch off autofocus.
− Set the object distance to
∞
.
− Set aperture-priority auto exposure mode.
− Choose an aperture as large as possible (i.e. small aperture value!).
Not all cameras provide these options. Please consult the Operating Manual of the camera used.
•
Loosen the set screw (Fig. 32/ 5 ).
•
Vary the camera lens/lens mount distance gradually, i.e. displace the sliding mount with camera on
lens mount in defined steps.
•
Zoom the camera lens through from wide angle (W) to tele position (T).
