Note - In the T-1924C, be sure that the floating stage is centered directly
over the sub-stage illuminator, so light comes through. - The floating
stage can actually cover up the sub-stage illuminator so no light comes
through.
Place a specimen slide on the stage of the microscope, and move the
specimen into place for viewing. First, put the 4x objective in position of
use. Using the coarse adjust knob (larger of two) raise the stage until it
will go no higher. Now looking through the eyepieces, lower the stage
(again using the coarse adjust), bringing the specimen into focus. Use
the fine adjust knob (smaller of two) to now sharpen the focus and attain
maximum resolution. Now rotate the 10x objective into place, and you
should only have to use the fine adjust to achieve a crisp focus (The
microscope is Parfocal). Now the 40x objective can be similarly utilized if
needed.
Note - on the T-1924C you may start with the 2x objective if you choose
to.
With coaxial focusing, both the coarse focus (large knob) and fine
focus (small knob) are on the same axis. Having both sets of knobs on
the same axis makes it easier to switch from one focus knob to the other
without moving eyes away from the eyepieces. Repeat this procedure
with each of the two microscope bases.
Now using the X-axis knob set for split screen, one can view the left
microscope specimen on the left, the right microscope specimen on the
right, or roll the knob and see only the left or the right specimens.
Specimen Manipulation
The mechanical stage of the T-1922C Cordless Comparison
Microscope, allows the user to control the movement of the specimen
slide on the X - Y axis. It consists of a slide holder and two sub-stage
knobs, one of which moves in the X direction (left & right), the other in the
Y direction (forward & backward).
The T-1924C comes with a "floating stage". Place the specimen on
the stage (use stage clips for a microscope slide), and then grasp the
stage between the thumb and forefinger, and move the whole stage,
specimen and all, left-right, forward-backward. Because of the
lengthened working distance of this microscope, it is not practical to have
a mechanical stage.
