The stage is set!  The stage of the microscope is the flat panel that accepts specimens for close examination.  The subjects

being scrutinized are usually mounted on a rectangular piece of transparent glass, (a slide) that is then secured to the stage which

is then illuminated from below. 

 

As shown here the electric illumination device is nearest to the bottom of the scope.  The device itself allows for regulating brightness

by way of a dial on the external power box (not shown).  But that's not all.  There is a tiny swiveling lens that adjusts light intensity

to aid in regulating contrast.

 

If that weren't enough, the device just below the stage further regulates the light that's to go through the hole in the stage.  Think

that's enough?  Nope.  Just in case the user prefers light from an outside source, included with the scope is a combination

flat and concave mirror that replaces the electric unit.  But there's ONE MORE option.  The microscope kit also comes with a frosted

glass disc for diffusing the light by eliminating shadows, AND a deep blue filter is supplied.  I'm not sure what that's used for.  My

theory is that the filter converts the reddish incandescence of the electric illuminator to that which simulates daylight.

 

One last thing:  Although this microscope has two eyepieces, stereoscopic viewing isn't possible because only one

corresponding objective lens can be used at a time.  However I have purchased a stereo microscope, and once it's received

I hope to post some 3-D microscopic views.

 

End of series.
