Stereo microscope usage skills include focusing, lighting, pupil distance adjustment and magnification selection.
Focusing skills
Coarse adjustment: First, turn the coarse adjustment knob to slowly lower the lens barrel until the objective lens is close to the sample surface. Be careful not to let the objective lens touch the sample to avoid damaging the objective lens or the sample.
Observation: Observe the sample through the eyepiece, slowly turn the coarse adjustment knob, and lift the lens barrel upward until you see a clearer image.
Fine adjustment: Use the fine adjustment knob to make fine adjustments until you get the clearest image. The fine adjustment knob has a smaller adjustment range and can control the focal plane more accurately.
Binocular adjustment: Some stereo microscopes have a binocular adjustment function, which can be adjusted according to the user's binocular vision difference, so that the images of the left and right eyes are completely overlapped to obtain the best stereoscopic visual effect.
Lighting skills
Choose the appropriate lighting method and light intensity: The combination of transmitted light and reflected light can achieve the best observation effect. Too strong or too weak light will affect the image quality.
Tips for adjusting pupil distance
Adjust the pupil distance: Adjust the distance between the eyepieces according to the user's pupil distance to ensure that both eyes can observe comfortably. When the two circular fields of view in the observation field overlap, the pupil distance has been adjusted.
Tips for selecting magnification
Select the appropriate magnification: Select the appropriate magnification according to the observation needs. The higher the magnification, the better. The appropriate magnification can achieve the best observation effect.
Other usage tips and maintenance suggestions
Cleaning: After use, wipe the lens and body with a clean soft cloth or special cleaner to keep them clean. Never use organic solvents to wipe the lens to avoid damaging the lens coating.
Dustproof: When not in use, cover the microscope with a dust cover to prevent dust from entering.
Storage: Store the microscope in a dry and ventilated place, away from direct sunlight and moisture.
