How to Use the 100X, 200X and 400X Lenses

Once you have the hang of using the 30X and 50X lenses, change to the 100X or 200X lens to
see the same objects under higher magnification. (Follow above instructions for changing
lenses.) You will find that the 30X/50X is best for looking at certain larger items, such as
fingerprints, rocks, etc., but the 100X/200X will allow much closer examination of small objects,
such as salt crystals, cells, and clothing fibers. Each of these higher powered lenses has a fine
focus mechanism due to the smaller field of view. This means that the higher the magnification,
the small the area (field) the lens can view at one time. For example, you can see an entire
fingerprint pattern with the 50X, but you will only see part of a few ridges with the 200X.
