Leica DM IRB manual MTV = objective magnification x tube factor Monitor diameter

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
adapter magnification	x ––––––––––––––––––––
	chip diameter of camera

Beamsplitting for photomicrography or TV microscopy

DM IRB 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).

DM IRB with side photo port and front port (DM IRB-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).
