The direction in which the stage moves depends on the orientation of the microscope. If the microscope is in the upright position, the stage will move in the same direction as the control knob. For example, if you turn the x-axis control knob to the right, the stage will move to the right. If the microscope is in the inverted position, the stage will move in the opposite direction of the control knob. For example, if you turn the x-axis control knob to the right, the stage will move to the left.
The coaxial stage controls are located on the front of the microscope, below the stage. They are typically two knobs, one for the x-axis and one for the y-axis. Some microscopes also have a z-axis control, which is located on the side of the microscope.
The coaxial stage controls are used to move the specimen on the stage so that it can be viewed under the microscope. By moving the stage, you can bring different parts of the specimen into view. You can also use the stage controls to center the specimen under the objective lens.
