Calculation of the magnification on the monitor

For all TV exits the magnification on the monitor

can be calculated with the following formula:

MTV = objective magnification x tube factor x

TV monitor diameter

x ––––––––––––––––––––

adapter magnification

chip diameter of camera

Beamsplitting for photomicrography

or TV microscopy

DMIRB with side photo port only and corre-

spondingly with one beamsplitter switch rod

(81.1).

– Image recording via phototube:

Switch rod pushed in = 100% light to the tube

(82.1).

– Image recording via side photo port:

Switch rod pulled out = 80% light to the side

port and 20% light to the tube (82.2).

DMIRB with side photo port and front port

(DMIRB-SLR) and correspondingly two beam-

splitter switch rods (81.1 and 81.2).

– Image recording via phototube or side port:

Use the upper switch rod (81.1) as for the

version with side photo port only.

Push the lower switch rod (81.2) in (82.3 and

82.4).

– Image recording via front port* (SLR/TV) or

phototube:

Upper switch rod (81.1) pushed in, lower

switch rod (81.2) pulled out = 50% light to the

front port and 50% to the tube (82.5).
