Viewing 3D Objects
As with viewing slides with the microscope, always begin your observation
with the 4X objective and increase magnification accordingly.
Focusing Tip
Only the 4X and 10X objectives may be used when viewing 3D
objects. The 40X objective is not suitable for use with the upper lighting due
to the focusing distance required.
For contrast, you may find it necessary to place certain specimens on an index
card or small piece of paper before centering them on the stage. When you
are using the top light, it will not be necessary for the opening in the stage to
be exposed for the lower light to shine through. Also, you do not want your
specimen to fall through the hole!
This application allows you to magnify and view countless everyday items like
small rocks, leaves, insects, flower petals, coins, stamps, jewelry and more.
Focusing Tip
A 3D specimen, like a small insect, will have different levels to
focus on; therefore the entire image may not seem clear at the same time.
Compare to a flat field, such as a postage stamp, where the specimen is all at
the same level which allows the microscope to focus on the entire field. With
a little practice, you can soon become an expert at observing all types of
specimens with the
