The rapid development of digital microscope in the field of industrial inspection
Digital microscopes are revolutionizing the field of industrial inspection. Space is at a premium in laboratories, so a system that can combine multiple microscopes into one is essential. Today, digital microscopes can do just that, with a magnification range covering a field of view from 22 mm to 42 microns. Its macro-to-micro capability makes it easy to observe samples at low magnifications, allowing them to see their properties in the context of their surroundings, before observing small areas at high magnification to see details. With an easy-to-operate user interface, even novices can quickly and easily obtain sample results using only one instrument. A typical inspection example that is challenging for conventional microscopes but which digital microscopes excel at is the observation of polished samples. Upright microscopes often struggle with polished samples because they are often not perfectly flat and level, making it difficult to keep the sample surface perpendicular to the optical axis of the microscope. Therefore, an inverted microscope whose optical axis is naturally perpendicular to the sample surface is often preferred. However, when using digital technology and motorized components, this limitation of upright microscopes can be compensated, opening up the possibility of further in-depth analysis. Integrating a digital microscope with advanced image analysis software also gives you the ability to customize the instrument. With the standard operating procedures and wizard-style operation functions provided by the DSX series digital microscopes, you can get your work done more easily than ever. Now, even users with relatively little training can perform many types of analysis, from grain analysis to complex particle classification.
1. The biological microscope should be placed in a dry and clean room to avoid moldy optical components, rusty metal parts, and dust. After the microscope is used, put it back into the box (cabinet), or cover it with a glass cover or a plastic sleeve, and put it into a dry operating agent.
2. Do not disassemble the components of the biological microscope by yourself; insert the eyepiece or cover the lens barrel to prevent dust from entering from the upper part of the lens barrel; do not touch or wipe the lens surface with your fingers. If there is dust, use a soft cloth first. Gently wipe off with a brush, and then wipe with a soft clean cloth, or use a lens cleaning paper dipped in a little xylene or petroleum jelly, but be careful not to draw streaks on the lens surface. If there is mild mildew on the lens, if you can't wipe it off with wipe paper, you can use a cotton swab dipped in a little mixture of 70% ethanol and 30% BMI to gently wipe it off.
3. Biological microscopes should not be placed together with corrosive acids, reduced or highly volatile chemicals, so as not to be corroded and shorten the service life. In principle, when observing specimens containing liquid, it is generally necessary to cover with a cover glass; if the liquid contains acid, alkali and other corrosive chemicals, the surrounding of the cover glass should be sealed with paraffin or Vaseline, and then observed . However, since this type of reagent is often used in the microscopic identification of traditional Chinese medicine, it is impossible to seal them all, so special care must be taken to prevent the liquid from flowing onto the stage and not sticking to the objective lens.
4. The biological microscope should not be exposed to direct sunlight, nor should it be placed near a stove or heating, so as to avoid degumming, deformation or damage of the lens and parts caused by drastic changes in temperature and temperature.
5. Cleaning of the objective lens of the biological microscope is limited to the outer surface. After the contact surface is contaminated by drugs, wipe it with a lens paper dipped in a little lens cleaning solution (do not use ethanol); if the back needs to be cleaned, use a soft brush to wipe it, or use a leather suction head to absorb the dust.
6. When turning the coarse and fine adjustment ratio aluminum to adjust the focus, the movement should be slow, do not crush the cover quilt, in order to prevent the objective lens and light collector from being damaged by controlled impact.
7. After using the oil lens, wipe off the cedar oil on the lens (you can wipe it with a little xylene on the lens cleaning paper, but note that the xylene cannot penetrate into the lens, otherwise the xylene will dissolve the adhesive between the lenses , causing the lens to fall off).
8. The surface of the reflector should be protected and cleaned. Do not let water, xylene or cedar oil penetrate to prevent the mercury from falling off the reflector.
9. If the mechanical part is not flexible, you can use a fine silk cloth dipped in xylene to wipe off the rust and greasy (ethanol is not allowed, because these solvents will corrode the paint), and then lubricate with a little liquid stone; do not force it when the screw is too tight Twist to avoid damage.
10. Sometimes when stains or foreign objects are found in the field of view of the biological microscope, you can turn the eyepiece first. If the stains rotate, you can confirm that the stains are on the eyepiece; otherwise, you can move the specimen. If the stains move, then the stains are on specimen sheets. If neither, the stain is on the objective lens, first pick up the front lens of the food mirror, and then check the rear lens. Clean according to the situation.
Sometimes a part of the field of view is not clear. This may be due to fingerprints or dust on the surface of the objective lens or the front lens of the eyepiece, or it may be that the specimen sheet is not well done or the microscope is used improperly. For example, the illumination system has not been adjusted properly, etc. Solve separately.
11. After using the biological microscope, all parts should be wiped clean, and the grid-connected objective lens should be turned into a figure-eight shape, then the lens barrel and light collector should be lowered and fixed, and then the mirror surface of the mirror should be placed in a vertical position.
