How to Adjust a Stereo Microscope
1. Adjust the hinges of the binocular tubes so that the distance between the eyepieces matches the interpupillary distance of the eyes.
2. Adjust the zero point on the eyepiece scale line to correspond to the white point on the eyepiece (if using an eyepiece micrometer, adjust the eyepiece with the eyepiece micrometer until the eye can clearly see the image of the eyepiece micrometer) .
3. Place the sample on the stage and illuminate it.
4. Adjust the magnification changer to the maximum magnification and focus on the sample details.
5. Adjust the magnification changer to the minimum magnification, and adjust the diopter compensators on the two eyepieces. If an eyepiece micrometer is already placed in one of the eyepieces, only the other eyepiece needs to be adjusted.
After adjustment, the details of the sample remain in focus throughout the entire zoom range without the need for adjustment.
Common problems and solutions of stereo microscope
1. The field of view is blurred or there is dirt. There may be dirt on the specimen, dirt on the surface of the eyepiece, dirt on the surface of the objective lens, and dirt on the surface of the working plate. According to the situation, the dirt on the surface of the specimen, eyepiece, objective lens and working plate can be cleaned.
2. The reason for the misalignment of the two images may be that the interpupillary distance is not adjusted correctly. Interpupillary distance can be corrected. If the double images do not overlap, it may also be that the diopter adjustment is incorrect. You can re-adjust the diopter. It may also be that the left and right eyepieces have different magnifications. You can check the eyepieces and reinstall the eyepieces with the same magnification.
3. If the image is not clear, it may be that there is dirt on the surface of the objective lens, please clean the objective lens.
4. If the image is not clear when zooming, it may be that the diopter adjustment and focus are not correct, and the diopter adjustment and focus can be re-adjusted.
5. If the bulb often burns out and the light flickers, it may be that the local line voltage is too high, the bulb is about to burn out and the wire is connected, please carefully check whether the voltage and the wire connection of the microscope are firm, if not, it may be the bulb If it burns out, the bulb can be replaced again.
