Adaptation Of Imaging Systems On Binocular Photo Tubes; Microphotography; Tv Adaptation; Calculation Of The Magnification On The Monitor - Leica DMIL Instructions Manual

Adaptation of imaging systems on binocular
photo tubes*
The binocular photo tubes provided for the Leica
DM IL can be used to adapt an imaging system,
e. g. video camera, reflex camera or automatic
photo system (e. g. Leica MPS 48/52).

Microphotography

Requirements for the adaptation of microphoto-
graphic equipment include a trinocular tube, a
HC PHOTO eyepiece adapter tube and HC PHOTO
eyepieces with 27 mm insertion diameter. If the
microphotographic equipment is not provided
with a special viewing port to limit the format, it
is necessary to use HC PLAN M eyepieces, i. e.
with focusable eyelens and photo graticule
inserted, in the binocular viewing port. For addi-
tional details, please refer to the manual
supplied with the photo equipment.
Without zoom magnification:
c-mount adapter 1x HC
c-mount adapter 0.63x HC
c-mount adapter 0.5x HC
c-mount adapter 0.35x HC
c-mount adapter 4x HC
With zomm magnification (Vario TV adapter):
c-mount, 0.32 – 1.6x HC
B-mount, 0.5 – 2.4x HC
B-mount, 0.5 – 2.4x HC

TV adaptation

Different adapters are available for connecting
TV cameras with c-mount and B-mount objec-
tive thread. The adapters listed in the table
below can be used on all trinocular photo tubes,
although some tubes require an additional photo
adapter tube. The picture area on the monitor
depends on the adatapter used and on the chip
size of the camera.

Calculation of the magnification on the monitor

The magnification V
calculated using the equation below or
measured with an object micrometer and a cm
scale.
V = Objective magnification x
