7. Stage upper limit stop adjustment
(Upper Stage Limit is preset at the factory; please only adjust if
necessary)
●
The Stage Upper Limit stop marks the stage position at which the
specimen is in focus i.e. by restricting the movement of the coarse focus
knob.
●
With the specimen in focus, turn the stage upper limit stop clockwise by
the provided hexagon wrench until it reaches the stop.
●
When the stage upper limit stop is in position, the stage cannot be raised
from that position.However, the ne focus knob can move the stage
regardless of the limit but will only lower the stage.
●
Lower the stage by coarse focus knob.

8. Use of condenser aperture diaphragm
●
Critical illumination relies on using the sub-stage condenser to produce a
focused image of the homogeneous light source in the plane of the
specimen in order to achieve an even illumination condition over the
entire eld of view.
●
The condenser aperture diaphragm is provided for adjusting the
numerical aperture (N.A.) of the illuminating system of the microscope, it
decides the resolution of the image, contrast, depth of focus and
brightness.
●
Turning down the diaphragm will lower the resolution and brightness but
increase the contrast and depth of focus.
●
An image with appropriate contrast in most cases can be obtained with
