Because of its many advantages, the microscope has a wide range of applications in various sectors of industry, agriculture and scientific research. If there are some problems during use, you can solve them yourself according to the actual situation. According to the actual usage, the common faults are: the field of view is blurred or there is dirt. The possible reasons are 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 actual situation, it can be solved by cleaning the dirt on the surface of the specimen, eyepiece, objective lens and working plate. The possible reason for the misalignment of the two images is that the interpupillary distance adjustment is incorrect, and measures to correct the interpupillary distance can be taken. The misalignment of the two images may also be due to incorrect diopter adjustment, which can be re-adjusted, or it may be that the magnification of the left and right eyepieces is different. Check eyepieces and reinstall eyepieces of the same magnification. 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. 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. If the light bulb often burns out and the light flickers indefinitely, it may be that the local line voltage is too high, and the light 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 It is the light bulb that is about to burn out, which can be solved by replacing the light bulb. The adjustment of the stereo microscope before use mainly includes several steps: focusing, diopter adjustment, interpupillary distance adjustment and bulb replacement. Each will be described below.

Microscope focusing: Put the working table into the mounting hole of the table on the base. When observing transparent specimens, use a frosted glass platform; when observing opaque specimens, use a black and white platform. Then loosen the fastening screw on the focusing slide, and adjust the height of the mirror body to make it roughly the same working distance as the magnification of the selected objective lens. After adjustment, the fastening screws must be tightened. When adjusting the focus, it is recommended to use a flat object, such as a flat paper with printed characters, a ruler, a set square, etc. Diopter adjustment: first adjust the diopter rings on the left and right eyepiece tubes to the 0 reticulated position. Normally, look through the right eyepiece tube first.
OLYMPUS BX51 turn the zoom handwheel to the lowest magnification position, turn the focusing handwheel and diopter adjustment ring to adjust the specimen until the image of the specimen is clear, then turn the zoom handwheel to the highest magnification position and continue to adjust until the specimen is clear. At this time, observe with the left eyepiece tube. If it is not clear, adjust the diopter ring on the left eyepiece tube along the axial direction until the image of the specimen is clear.

2. Interpupillary distance adjustment: Pull the two eyepiece tubes to change the exit pupil distance of the two eyepiece tubes.
