High Power Microscopes Maintenance

1. regular maintenance
(1) The moisture-proof, if is indoor humidity, optical lens is easy to mold of Health, the Health and fog. Once the health optical lens mold, it is difficult to remove. The lens inside the high power microscopes because of the inconvenience wipe, wet their scams. After damp mechanical parts, easy to rust. In order to moisture, storage microscopy, in addition to select dry room, the storage place should be away from the wall, the ground and wet sources. High power microscopes box should be placed 1 to 2 bags of silica gel desiccant for. And often carried out on the silicone baking. Changes in its color pink, it should promptly baking, baking and then continue to use.
(2) The dust on the optical elements surface, not only affects the light to pass through, but also amplified by the optical system, will generate a great smirch affect observation. Dust, sand falling into the mechanical parts, will also increase the wear and tear, caused by movement blocked, against just as great. Therefore, we must always maintain a clean high power microscope.
(3) anti-corrosion high power microscopes can not have a corrosive chemical reagents together. Such as sulfuric acid, hydrochloric acid, alkali and so on.
(4) The heat-resistant heat-resistant main purpose of high power microscopes is to avoid thermal expansion and contraction caused by the opening of plastic and fall off the lens.
2, optical system of the cleaning
Normally on the high power microscopes parts, the various optical surfaces clean usually use a clean brush or lens cleaning paper wipe.
Ma Budiao the lens on the dirt, grease, or fingerprints, the lens mold of Health, the Health and fog and long-term re-used after the closure, they all need to be polished before use.
(1) wipe the scope eyepiece and condenser allowed to open the wipe. Lens due to structural complexity, the assembly of specialized equipment they need to correct in order to restore the original precision, it is strictly prohibited open the wipe.
Demolition eyepiece and condenser must pay attention to the following points:
a, be careful.
b, demolition, you should mark the relative position of each component (available on the case marking on the dash), the relative order and the lens of the positive and negative, to prevent heavy equipment when the mistake.
c, operating environment should be kept clean and dry. Demolition eyepiece, as long as spin out from the upper and lower ends of two lenses can be. Eyepiece field of view within the optical field can not be moved. Otherwise, the field of view will blur the distinction. After the condenser unscrew lens on it is prohibited to further break down. Because the lens is Oil, the factory well-sealed, and then break the seal would undermine the performance of its damage.
(2). Cleaning method is like this, first, with a clean brush or hair lens surface of the ball to remove dust. And then use a clean cloth from the lens center to the edge of beginning to make spiral-shaped one-way movement. Cawan time that flannel for a place and then wipe up wipe up. If the lenses of the high power microscope have oil stains, dirt, or fingerprints and so indelible, the available switchgrass be wrapped cotton, dip a small amount of alcohol and ether mixture (alcohol 80%, ether 20%) wipe. If there is heavier Mildew can not be removed when you become moldy, or can be used wet cotton swab dipped in water after the viscosity of calcium carbonate powder (content of 99% or more) to wipe. Cleaning, the powder should be cleaned. Lens is wipe can be used lenses to observe the light reflection on the check. It should be noted that the former sure to wipe the dust addition to the net. Otherwise, the dust in the sand will be designated mirror starting grooves. Are not allowed with a towel, handkerchief, clothing, etc. to wipe the lens. Alcohol-ether mixture is not used too much, so the Ministry of the liquid adhesive into the lens to make lens unglued. Lens surface with a layer of translucent violet blue film, do not be mistaken for dirt, wipe.
(3), cleaning the mechanical parts of high power microscope
The Surface painting part, can be used cloth. But you can not use alcohol, ether and other organic solvent wipe to avoid paint stripping. If rust does not paint the part that can be used wipe cloth dipped in petrol. Wipe grease can be re-Shang Hao protection.
