User Manual

Finally, you can turn the nosepiece to the 40X objective, giving you a 400X

magnification of your slide. When increasing magnification, always remember that

the higher the magnification, the closer the objective must be to the specimen

being observed.

Focusing Tips The 40X lens will appear to be almost touching the slide. This is

normal. Always move the focusing knobs very slowly to avoid breaking the slide

with the objective.

When changing slides, move the stage to its lowest position, lift the clips to

remove and replace slides and begin observing with the 4X objective again.

Stereo Microscope Use (for solid objects)

As with the compound microscope, always begin your observation with the 4X

objective and increase magnification accordingly.

Note: Only the 4X and 10X objectives may be used when viewing solid

specimens. The 40X lens is not suitable for use with the upper lighting due to the

focusing distance required. The 40X lens must be too close to the specimen and

will not allow any light to reach the specimen.

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 upper 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 Tips A three dimensional 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 My First Lab

Mini Duo-Scope.
