4.3. Objectives
There are different kind of objectives, e.g. M-Plan
∞
or achromatic objectives in different
magnifications (5x ; 10x ; 20x ; 50x)

4.4. Colour
filter
A blue matted glass with a diameter = 32 mm
can be done into a filter holder, so that the light
becomes daylight similar (if halogen light
illumination is in use). In order to change
generally the colour of the lighting, colour filters
are used, which are in a similar holder like the
blue matted glass.
5. Intermediate
Tubes
5.1. Angled
tube
The angled tube is used in connection with the
straight binocular tube. The tube is equipped with
a 30° angle and image erection (IE). It is
attached between the centre section of the
microscope and the straight binocular tube. (for
160mm Objectives)

5.2. Photo-/TV
tube
If binocular observation and photographic or
video-technical recording should take place
simultaneously, you can use the photo tube. The
tube is equipped with a 30° angle and image
erection (IE).The photo tube is set on the centre
part of the microscope and has connections for
the straight binocular tube and a photo or TV
adapter.

Beyond that a further Photo-/TV tube with a firm
division ratio of 80/20 are available, i.e. 80%
of the light are used for visual observation and
20% for the photographic reproduction or the
video image. (for 160mm Objectives)
