Limit Stop Knob
The limit stop is designed to prevent impact between objective and slide. You may
loosen the limit-stop knob in order to give yourself the full range of motion for fine tuning
the focus when using the 40X and 100X objective lenses.
When the limit stop is off you will be able to damage the microscope or the glass slide.
For safety, engage the limit stop once you have it close or in contact with the objective
(if using oil contact is required).
Magnification
Microscopes have a two lens system. Total Magnification is the power of two lenses
multiplied together.
E.g.: (10X Eyepieces) x (4X Objective) = 40X Total Magnification
Mechanical Stage
A Mechanical Stage is a flat mechanism that sits on top of
the stage and allows the viewer to move a specimen small
distances - a task that is otherwise difficult at higher
magnifications. Most mechanical stages are equipped with
an X and Y axis so the viewer can see how far the slide
has moved.
Mechanical Stage Control
The mechanical stage control moves the stage,
mechanically moving the slide along an X and Y axis for
optimal positioning.
The top ring moves the stage forward and backward. The
bottom ring moves the stage from left to right.
