What Are the Best Tips for Compound Microscope Use?

Stereo microscope, also known as "solid microscope" or "dissection microscope", can produce upright three-dimensional images of space when observing objects. It has strong stereo sense, clear and wide imaging, and long working distance, and it is a conventional microscope with a very wide range of applications. Easy to operate, intuitive, and high verification efficiency, suitable for inspection of the electronics industry production line, verification of printed circuit boards, verification of welding defects (printing misalignment, sag, etc.) in printed circuit components, verification of single-board PC, vacuum fluorescence Verification of display VFD, etc., equipped with measurement software can measure various data.

Stereo microscope

Stereo microscope is also called "

By a shared elementary

(1) After installing the microscope, plug in the power plug after ensuring that the power supply voltage is consistent with the rated voltage of the microscope, turn on the power switch, and select

(1) The instrument should be protected from direct sunlight, high temperature, humidity, dust and acid and alkali gas corrosion;

(2) The working room should be kept clean frequently, and the dust cover should be covered after using the instrument;

(3) The microscope should be placed on a solid and stable workbench;

(4) Avoid contamination of the lens by dirt or fingers during operation,

1. The left and right beams in the binocular tube are not parallel, but have a certain included angle-body angle of view (usually 12 degrees-15 degrees), so the imaging has a three-dimensional sense;

2. Like upright for easy manipulation and dissection, because

Because of its many advantages, stereo microscopes have been widely used in various sectors of industry, agriculture and scientific research. If there are some problems during use, you can solve them according to the actual situation. According to the actual use, common faults are: blurred field of view or dirt, 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 work plate. According to the actual situation, clean the dirt on the surface of the specimen, eyepiece, objective lens and work plate. The possible reason for the misalignment of the two images is that the interpupillary distance can be adjusted by taking the correct interpupillary distance. The misalignment of the two images can also be caused by the incorrect adjustment of the diopter. The dioptric adjustment can be taken again. Check the eyepiece and refit the eyepiece of the same magnification. If the image is not clear, there may be 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 vision adjustment is incorrect and the focus is incorrect. You can perform the vision adjustment and focus again. If the bulb often burns out and the light flickers, the local line voltage may be too high, the bulb will soon burn out, and the wire connection is poor. Please carefully check the voltage and the wire connection of the microscope. If not, It may be that the bulb is about to burn out. Replace the bulb.

The adjustment of the stereo microscope before use mainly includes: focus adjustment, diopter adjustment, interpupillary distance adjustment and bulb replacement. Each is described below. Focusing: Place the worktable into the platen mounting hole on the base. When observing transparent specimens, use frosted glass platen; when observing opaque specimens, use black and white platen. Then loosen the fastening screws on the focusing slide, and adjust the height of the lens body to a working distance that is generally consistent with the magnification of the objective lens selected. After adjustment, tighten the fastening screws. When focusing, it is recommended to use flat objects, such as flat paper printed with characters, rulers, triangle plates, etc. Diopter adjustment: first adjust the diopter circles on the left and right eyepiece tubes to the 0 scale line. Normally, look through the right eyepiece tube first. Turn the zoom handwheel to the lowest magnification position, turn the focus zoom wheel and the vision adjustment ring to adjust the specimen until the specimen image is clear, then turn the zoom handwheel to the highest magnification position and continue to adjust until the specimen image is clear So far, observe with the left eyepiece tube. If it is not clear, adjust the circle of vision on the left eyepiece tube in the axial direction until the image of the specimen is clear. Interpupillary distance adjustment: You can change the exit pupil distance of the two eyepiece tubes by pulling the two eyepiece tubes. When the user observes that the two circular fields of view completely coincide, the interpupillary distance has been adjusted. It should be noted that due to the differences in individual vision and eye adjustments, different users or even the same user using the same microscope at different times should be individually adjusted for parfocal adjustment in order to obtain the best observation effect. Regardless of whether you are replacing the upper light bulb or the lower light bulb, be sure to turn off the power switch and unplug the power cord from the power outlet before replacing. When replacing the upper light source bulb, first unscrew the knurled screws of the upper light source light box, remove the light box, then remove the bad bulb from the lamp holder, replace the good bulb, and then install the light box and knurled screw. When replacing the light source bulb, remove the frosted glass plate or black and white platen from the base, then remove the bad bulb from the lamp holder, and replace the good bulb; then install the frosted glass plate or black and white platen. . When replacing the bulb, please wipe the bulb bulb with a clean soft cloth or cotton yarn to ensure the lighting effect.
