Common problems with stereomicroscopes and how to solve them
Stereoscopic microscope, also known as solid microscope or dissecting microscope. A binocular microscope refers to a visual instrument with a positive stereo sense, which observes objects from different angles and causes stereo sensation in both eyes. The observation body does not require any processing or production, and can be directly placed under the lens with lighting for observation, as if it is upright, making it easy to operate and dissect. The field of view has a large diameter, but the observation object requires a magnification of less than 200 times. The characteristics of a stereo microscope are as follows: the left and right beams in the binocular tube are not parallel, but have a certain angle - the volumetric angle is generally 12 ° to 15 °, so the imaging has a three-dimensional sense. This is because the prism below the eyepiece inverts the image; Although the magnification is not as good as a conventional microscope, it has a long working distance, a large depth of focus, and is easy to observe the entire layer of the object being tested, with a large field of view diameter.
Common problems and solutions for stereomicroscopes:
1. The field of view is blurry or 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 workboard. Clean the dirt on the surface of the specimen, eyepiece, objective, and workboard according to the situation.
2. The reason for the non coincidence of dual images may be due to incorrect adjustment of pupil distance. Can adjust pupil distance. If the dual images do not overlap, it may be due to incorrect visual adjustment and can be adjusted again. Alternatively, if the magnification of the left and right eyepieces is different, check the eyepieces and reinstall them with the same magnification.
3. If the image is unclear, it may be due to 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 due to incorrect visual adjustment and focusing. You can adjust the visual angle and focus again.
5. If the light bulb frequently burns out and the light flickers incessantly, it may be due to the local line voltage being too high, the light bulb is about to burn out, and the wire connection is poor. Please carefully check whether the voltage and the wire connection of the microscope are firm. If not, it may be because the light bulb is about to burn out and the bulb can be replaced.
