Focus
Probably the most important thing to look for in a microscope is its ability
to get an image into perfect resolution or focus -- and stay that way.
BestScopes.com offers you clear focusing that will make your time spent with
your microscope enjoyable and satisfying. With our scopes your children
will be stimulated (instead of being frustrated) towards more creativity in
their scientific studies when they can easily focus on an image.
All microscopes have a coarse focus knob that brings the specimen into
perfect focus very quickly. For families with young children this may be all
you will need. However, when working at higher magnifications a fine focus
knob is necessary so that the depth or thickness of a specimen
will appear sharp and clear. We highly recommend any of our
Observer or
Revelation scopes as they all have both
the coarse and fine focus knobs.
All our scopes have two more very important focusing features you won't want
to be without -- a slip clutch, and parfocal ability. A slip clutch (a
"notched" system that the microscope's stage "rides" on) keeps the stage from
"slipping" so you can keep perfect focus. Parfocal means the object
in view will stay in focus when you rotate (change) the objectives! Pretty
neat, huh?
