Experiments with the Handheld
Digital Microscope
Experiment No. 1:
Black and White Print
Objects:
1. a small piece of paper from a news-
paper with a black and white pic-
ture and some text,
2. a similar piece of paper from a
magazine.
Place both pieces of paper next to
each other on a table. Set your micro-
scope to the lowest magnifi cation and
place it on the pieces of paper, fi rst
on the newspaper and then on the
magazine.
Compare: The letters on the news-
paper look frayed and broken, since
they are printed on raw, low-quality
paper. The letters on the magazine
look smoother and more complete.
The pictures in the newspaper are
made up of many tiny dots, which ap-
pear slightly smudgy. The pixels (half-
tone dots) of the magazine picture are
clearly defi ned.
Experiment No. 2: Color Print
Objects:
1. a small piece of color printed
newspaper,
2. a similar piece of paper from a
magazine.
Place both pieces of paper next to
each other on a table. Set your micro-
scope to the lowest magnifi cation and
place it on the pieces of paper, fi rst
on the newspaper and then on the
magazine.
Compare: The colored pixels of the
newspaper often overlap. Sometimes,
you'll even notice two colors in one
pixel. In the magazine, the dots ap-
pear clear and rich in contrast. Look
at the different sizes of the pixels.
