Five incorrect ways to use a microscope
5 incorrect ways to operate a microscope
1. Place the microscope next to the sink or window in the laboratory. Moisture and dust are the killers of the microscope. The wrong placement method and location will greatly shorten the service life of the microscope.
2. Beginners of microscopes have little understanding of its basic principles and structure. Rough manipulation can also be fatal to the vulnerability of the microscope. For example: moving it frequently, using too much force when picking up and placing it, using force to raise and lower the focusing system when adjusting the focus, failing to adjust the focus and interpupillary distance correctly, etc.
3. The working distance of high-magnification lenses is usually very short, and improper operation can damage the high-magnification lenses. For example: some operators do not wipe the 100X oil lens clean or do not wipe it after use, which is a bad usage habit.
4. When changing the objective lens, operators often rotate the objective lens directly. Little do they know that this operation will affect the coaxiality and parfocality of the optical axis. The correct way to use it is to turn the nosepiece to get the desired observation objective.
5. If you open the condenser or field diaphragm too large or too small, and adjust its position too high or too low, you will not be able to obtain microscopic images with the best resolution and sharpness. In short, to use the microscope well to get the best microscopic images, you should understand and observe more, so that you can become a master of the microscopic world.
Microscope maintenance
1. Regular maintenance
(1) Moisture-proof If the room is humid, optical lenses will easily become moldy and foggy. Once mold gets on your lenses, it's difficult to remove. Because the lenses inside the microscope are inconvenient to wipe, moisture is more harmful to them. Mechanical parts are prone to rust when exposed to moisture. In order to prevent moisture, when storing the microscope, in addition to choosing a dry room, the storage location should also be away from the wall, the ground, and away from moisture sources. 1 to 2 bags of silica gel should be placed in the microscope box as a desiccant. And bake the silicone often. After its color turns pink, it should be baked in time and then used again.
(2) Dust falling on the surface of dust-proof optical components not only affects the passage of light, but also creates large stains after amplification by the optical system, affecting observation. Dust and sand falling into mechanical parts will also increase wear and hinder movement, which is also very harmful. Therefore, the microscope must be kept clean regularly.
(3) Anti-corrosion The microscope cannot be placed together with corrosive chemical reagents. Such as sulfuric acid, hydrochloric acid, strong alkali, etc.
(4) Heat protection The purpose of heat protection is mainly to prevent the lens from opening and falling off due to thermal expansion and contraction.
