Using Filters
The Ultimate Home
microscopes come with blue,
green, and yellow filters that
can be placed in the filter
holder located below the iris
diaphragm. Use the following
procedure to insert the filter:
1.
Underneath the iris diaphragm there is a tiny
filter holder knob. Use this to swing the filter
holder out from under the diaphragm.
2.
Place the filter in the holder, and swing back
into place.
3.
Adjust focus and diaphragm normally.
MI-5000DHD Model
Dual Teaching Head
The MI-5000DHD model comes with a dual
teaching head. In addition to the inclined
eyepiece, it has a
vertical eyepiece that
can be used for
simultaneous viewing
or digital camera
photography. The
vertical eyepiece is
equipped with a
diopter, which is used
to adjust for focusing
differences between
the two people using the different eyepieces.
These adjustments vary from person to person.
1.
Have the person using the inclined eyepiece
focus the microscope.
2.
Have the person using the vertical eyepiece
rotate the diopter adjustment (the knurled
band) until the specimen is also in focus for
his or her eyes.
Adding a Digital Camera
While a digital camera can be used with the
other models, it works especially well with the
dual teaching head.
1.
A digital
camera
package (our item MI-
DC1000) will include a digital camera that
fits over the vertical eyepiece. Focus the
microscope using the inclined eyepiece, and
then use the diopter to adjust the camera
image until it is sharp and clear on your
monitor.
2.
A digital
eyepiece
package (our item MI-
DIGICAM) will include a digital camera
eyepiece that will replace the vertical
eyepiece on your microscope. To remove
the eyepiece, loosen the tiny screw until you
are able to lift the eyepiece out (you will not
need to unscrew it completely).
MI-5000BIN Model
The MI-5000BIN model comes with a
Seidentopft binocular head for enhanced image
examination and extended viewing comfort.
Installing the Binocular Head
The binocular head is shipped in a separate
carton, and will need to be installed using the
following procedure:
1.
Remove the binocular head carefully from
the packaging.
2.
Loosen the set screw
located above the
nosepiece.
3.
Set the binocular head
firmly in place, making
sure the v-groove fits
against the two fixed
screws and flush against
the head support, and
tighten the set screw.
4.
The screw should be
tight enough that the head doesn’t wobble,
but loose enough that it can still rotate 360º.
Using the Binocular Head
To use this feature to the best advantage,
you must set the interpupillary distance to match
the distance between the pupils of your eyes.
You must also adjust the diopter to compensate
for focusing differences
between your
eyes. Each user
of the microscope
must make these
adjustments for his
or her own eyes.
To do so, follow
these steps:
1.
Start by focusing a small specimen in the
center of the viewing field using the 10x
objective. The iris diaphragm should be in
the closed position.
2.
Focus your eyes on the specimen.
3.
Pull your eyes back from the eyepieces
about 1”. In your peripheral vision you will
