step 1
Place the microscope on a workbench platform that is comfortable for the operator, then turn on the reflected light (surface light), put a pattern, such as a coin, on the microscope base, turn the zoom knob of the microscope to the lowest magnification, and find it by adjusting the lift group. Approximate focal plane (optimal imaging plane).
Step 2
Adjust the observation pupil distance of the eyepiece and adjust the diopter on the eyepiece to find the best focal plane.
Step 3
Using the above method, gradually increase the magnification of the zoom knob, adjust the lift group of the microscope appropriately, and gradually find the focal plane with the maximum magnification. During the adjustment process, please use the obvious reference point on the coin_ to compare the clarity of the image.
Step 4
Rotate the zoom knob to the lowest magnification, there may be some out of focus. At this time, please do not adjust the lift group to focus, just adjust the diopter above the two eyepieces to adapt to the observation of the eye (diopter varies from person to person). At this point, the microscope is already in focus, that is, the microscope is zoomed from high magnification to low magnification, and the entire image is in the focal length. For the same sample, we don't need to adjust other parts of the microscope, just turn the zoom knob to easily observe the sample with zoom.
