Performance data of tubes
The tube changer is the same as with the
upright microscope stands.
The tubes can be rotated and changed.
DM ILB binocular tube
The binocular tube consists of a body with the
tube changer ring attached to the lower side.
The tube lens has a factor of 1x. The Siedentopf
binocular tube permits to adjust the inter-
pupillary distance from 55 mm to 75 mm while
maintaining the tube length. The viewing angle
is 45°. The tube has an adjustable eyepiece
tube. It offers a field of view number of 20. When
intermediate tubes are used, the maximum
possible field of view number is 18 (e. g. when
using the drawing facility).

DM ILT trinocular tube
The trinocular tube consists of a body with the
tube changer ring attached to the lower side.
The tube lens has a factor of 1x. The Siedentopf
binocular tube permits to adjust the inter-
pupillary distance from 55 mm to 75 mm while
maintaining the tube length. The viewing angle
is 45°. The tube has an adjustable eyepiece
tube. It offers a field of view number of 20. When
intermediate tubes are used, the maximum
possible field of view number is 18 (e. g. when
using the drawing facility or the multi-discussion
facility).
The lateral documentation port is to be fitted
with HC components only.
The tube contains a switchable mirror with two
positions:
a) 100 % of light directed to binocular tube
b) 100 % of light directed to photo tube
The optical axis of the documentation port is
offset to the left by 88 mm. This offers a free
view of the specimen when using this tube.
