Ants (eye)
This image of an ant (eye) was captured using an electron microscope that illuminates with a beam
of accelerated electrons. I used a 15kV accelerating voltage at the middle position in order to produce a
clear, distinct, and observable image which is neither brilliant nor dark. Then there's the spot size, which
is around 5nm, since as the magnification increases, we should move to a smaller spot size, which
produces better results for high-resolution images, allowing us to analyze and describe even the tiniest
features of the specimen. Lastly, I chose 8mm for the z height distance because it is recommended for
high magnification images to produce the sharpest image.
Moth proboscis 2
Unlike ants, which was captured at a high magnification. The image of the moth proboscis was
taken at a low magnification because I wanted to observe more of the species surface area. I chose a 20kV
electron microscope configuration to obtain a good bright image since I discovered that if I used a lower
kV, the tip of the moth proboscis would not have a clear, bright, and detailed appearance. Then, for the
spot size, I chose the larger spot size of 20nm because I learned that changing to the larger spot size at
low magnification produces better results image that focus on the larger characteristics of the specimen.
Finally, I chose 20mm for the z height distance since it is recommended for low magnification images that
require a large sample area to focus on at the same time.
