Tubes
• All accessory tubes which fit between the optics carrier and
the binocular tube are fitted in the same manner.
• In the dovetail ring of the optics carrier is a locating screw
which must engage the notch in the accessory (page 35).
This is best accomplished by moving the accessory slightly
from side to side.
̈ Release the clamping screw.
̈ Insert the accessory tube into the dove-
tail ring in the same manner as the binoc-
ular tube (page 35) and move it slightly
from side to side until the locating screw
engages the notch.
̈ Retighten the clamping screw.
̈ Fit the binocular tube on the accessory
tube in the same manner.
Double-iris diaphragm
A double-iris diaphragm is built into the MZ16 and MZ16 A. It is
operated by means of a knurled ring. A separate double-iris
diaphragm is available as accessory for the other instruments.
The double-iris diaphragm for MS5–MZ12
5
can be inserted between optics carrier and
binocular tube or video/phototube.
Set the lever to OPEN: The double-iris
diaphragm (aperture diaphragm) is open.
The depth of field increases as the lever
is moved from OPEN to 1. Remember,
however, that
– brightness decreases, so exposure times become longer
– resolution deteriorates.
