glass (available in a well sorted hobby shop) perpendicularly
at the edge of the water drop, so that the water runs along the
cover glass edge. Lower now the cover glass slowly over the
water drop.
DANGER!
Be extremely careful when using the knives/
scalpels or the MicroCut. There is an increased
risk of injury due to the sharp edges!
6. Experiments
If you made yourself familiar with the microscope already, you
can accomplish the following experiments and observe the
results under your microscope.
6.1 Newspaper print
Objects:
1. A small piece of paper from a newspaper with parts of a
picture and some letters
2. A similar piece of paper from an illustrated magazine
Use your microscope at the lowest magnification and use the
preparation of the daily paper. The letters seen are broken out,
because the newspaper is printed on raw, low quality paper.
Letters of the magazine appear smoother and more complete.
The picture of the daily paper consists of many small points,
which appear somewhat dirty. The pixels (raster points) of the
magazine appear sharp.
6.2 Textile fibers
Items and accessories:
1. Threads of different textiles: Cotton, line, wool, silk, rayon,
nylon etc..
2. Two needles
Each thread is put on a glass slide and frayed with the help of
the two needles. The threads are wetted and covered with a
cover glass. The microscope is adjusted to a low magnifica-
tion. Cotton fibres are of vegetable origin and look like a flat,
turned volume. The fibres are thicker and rounder at the edges
than in the centre. Cotton fibres consist primary of long, col-
lapsed tubes. Linen fibres are also of vegetable origin; they
are round and run in straight lines. The fibres shine like silk
and exhibit countless swellings at the fibre pipe. Silk is of
animal origin and consists of solid fibres of smaller diameter
contrary to the hollow vegetable fibres. Each fibre is smooth
and even and has the appearance of a small glass rod. Wool
fibres are also animal origin; the surface consists of structures
which overlap like shingles, and appear broken and wavy.
If it is possible, compare wool fibres of different weaving
mills. Consider thereby the different appearance of the fibres.
Experts can determine the country of origin of the wool by
microscopic observation. Rayon (artificial silk) is manufactured
by a long chemical process. All fibres show hard, dark lines on
the smooth, shining surface. The fibres ripple themselves or
crinkle after drying in the same condition. Determine common
features and differences by examining many different fibres.ṛ
7. Setup MicrOcular
NOTE!
The MicrOcular only works without the Barlow
lens supplied. Magnification setting is changed
by using the MicrOcular and must be reset by
focussing anew
Remove the Barlow lens (Fig. 2, 2) with the currently used eyepiece
from the tube (Fig. 2, 4) and put the MicrOcular (Fig. 4, 3) in place
instead.
.
8. Installation and use of the software
NOTE!
Please do not yet connect MicrOcular and
your PC. Please go through the items below in
sequence.
8.1. Software and Installation Information
A software CD is included with your microscope. The software
and drivers on this CD must be installed on your computer in
order to use your MicrOcular. Once you connect the MicOcu-
lar to your computer after installation, you can view pictures
on and save them to your computer using Photomizer SE. To
install the software and driver correctly, simply follow the in-
stallation steps.
8.2. Installation der Software
1. Important: Before inserting the CD, first plug the USB cable
into the USB port on your PC. Windows will now recognize
the new device, and will indicate this in a notification win-
dow. Now please click on "Cancel", since we will have the
driver for the device automatically installed later.
2. Now insert the CD-ROM that came in your package into the
CD/DVD drive of your computer. The installation menu starts
automatically. If it does not, go to the Windows explorer
and select the CD/DVD drive (most of the time, it's the "D"
drive, but it can have another letter). From there, start the file
"menu.exe" by double-clicking with the left mouse button.
8.2.1. Driver installation
To install the driver software, click on the menu point "Install Driv-
er" with the mouse cursor. Then follow the installation program
instructions.
During the software installation the correct driver for your oper-
ating system will be installed automatically. No manual input is
needed. In rare cases the device may not be recognised by your
computer. As a rule you need then only install the driver manu-
ally from the CD. If this fails please refer to the troubleshooting
chapter that follows.
8.2.2. Installation of the Image Editing Software
Photomizer SE
The image editing software "Photomizer SE" is located on the
software CD. You can edit your pictures here.
1. To install the software, click once on the menu point "Install
Software" with the left mouse button.
2. The Photomizer Software requires Microsoft .NET Frame-
work 3.5, which it will install if it is not already on your sys-
tem. If it is already on your system, you may skip to step 5.
3. In the welcome window, please accept the Microsoft license
agreement, and then click "Install". The installation can take
a few minutes.
4. As soon as everything is installed, click "Finish".
5. Now you will be presented with a choice, in which you can
choose your language.
Make your selection and confirm it by clicking „OK".
6. When you see "Welcome", click on „Next".
7. In the next window, you will be asked for the „Destination
Folder". Here, just click on „Next".
8. Now, the window with the Setup-Status will appear – here, a
progress bar will inform you about the ongoing installation.
This process can take a few minutes.
9. The window "Photomizer is being installed" appears. Click
on "Finish". The installation ends.
TIP:
i
To use the MicrOcular long-term we recommend
it always be connected to the same USB port.
