vation with a microscope. Set one of these
permanent slide preparations onto the micro-
scope stage (7). Push the slide underneath
both slide clips on the microscope stage, so
that nothing can move about during the obser-
vation. Then, turn the light to substage illumina-
tion (8) by pressing the On/Off button for the
light (16) as described in section 3.1. In the
next step, adjust the permanent slide so that
the observation object is clearly visible on the
monitor, in the preview area of the camera soft-
ware. Now, slowly turn the focus adjustment
knob (11) left or right until the image depicted
is in focus. By pushing multiple times on the
buttons for light brightness (+/-) (15), you can
set the illumination such that the fine details of
the observation object appear clearly on the
monitor as well.
If you would like to switch to a higher magnifi-
cation, turn the magnification adjustment knob
(3) to the left, to the position "80x" or "350x".
Important:
Each time you adjust the magnification, you
must also use the magnification adjustment
knob (3) to change the focus.
3.5.1 Observing Opaque Objects
If you would like to observe opaque objects
with this microscope, the object must be lit
from above. Therefore, use the On/Off but-
ton for the illumination (16) to set the lighting
to surface illumination (5), as described in
section 3.1. Place the observation object on
the small, round disk in the middle of the mi-
croscope stage. Using the focus adjustment
knob (11), focus the image. It will also then
appear in focus on the monitor. You might
have to move the observation object around
a little bit so that it is displayed properly on
the monitor. By pushing multiple times on the
buttons for light brightness (+/-) (15), you can
set the illumination such that the fine details of
the observation object appear clearly on the
monitor as well.
The Digital Microscope allows you to observe
objects with a height of up to 6 mm.
Tip:
If you are observing objects that are only
slightly transparent (e.g. minerals, grains of
sand, etc.), you can improve the picture qual-
ity by using surface and substage illumination
at the same time (section 3.1.). Illumination
from both directions is achieved with the On/
Off button for the light (+/-) (15).
Important:
If you turn on the illumination on the micro-
scope in a very bright room or near a window
on a sunny day, the image on the monitor can
appear much too bright. This is because the
camera is very sensitive. Too much light thus
overpowers the fine details of the observation
object. In this case, you must completely shut
off the light on the Digital Microscope, so that
all the details will become visible again on the
monitor.
