Compound microscope is assembled from lenses.
6A70.10 • E+30+55
Compound microscope is assembled from lenses. In step 1, a small illuminated arrow is focused by a lens (f.l. +8") onto a translucent screen. The arrow is inverted and enlarged. The video camera focuses on the arrow image and displays it on the monitor. In step 2, a lens (f.l. +5") is placed less than a focal distance of the screen. The arrow image is enlarged even more and displayed on the monitor. The translucent screen can be removed to show that it is useful only for fine-tuning the apparatus and is not necessary for the functioning of the microscope.
