The total magnification in the microscope, the
reproduction ratio on the photograph or TV
image can be quickly and easily measured with
a scale and calculated.
Imp ortant: For normal viewing without the macro
mirror housing or macrodual zoom, put on the
cover to avoid disturbing overlay effects.
The mirror housing (67.11) can be rotated through
360°, for example to alter the angle at which the
photograph is taken. This is done by loosening
the Allen screw.
The intermediate image magnification M
macro object can be worked out from the
eyepiece field of view (see page 43) and the
diameter of the object field (measured with a
graduated ruler) as follows:
M = z. B.

Viewed with a 10x eyepiece, this intermediate
image of 0.125x gives a total magnification of 1.25x
in the microscope eyepiece (0. 1 25 x 10 = 1.25).

magnifications of the photo eyepiece and

intermediate image magnification 0.125x
photo projection lens 8x
large-format attachment 1.25x
0.125 x 8 x1.25 = 1.25x
The total magnification at the 4 x 5'' large-format
camera of the DM LD would therefore be 1.25x.
