1, regular maintenance (1) Moisture-proof, if the room is wet, the optical lens is prone to mildew and fog. Once the lens is mildewed, it is difficult to remove. The lens inside the microscope is more harmful because it is inconvenient to wipe. Mechanical parts are prone to rust after damp. In order to prevent moisture, when storing the microscope, in addition to the choice of dry room, the storage location should also be away from the wall, off the ground, away from the wet source. 1 to 2 bags of silica gel should be placed in the microscope case as a desiccant. And often bake silica gel. After the color becomes pink, it should be baked in time and then used after baking. (2) Dustproof, the surface of the optical component falls into the dust, which not only affects the passage of light, but also enlarges the optical system to generate a large stain, which affects the observation. Dust and sand fall into the mechanical part, which also increases wear and tear, causing movement to be blocked and the damage is also great. Therefore, the microscope must always be kept clean. (3) Anti-corrosion, the microscope cannot be placed together with corrosive chemicals. Such as sulfuric acid, hydrochloric acid, strong alkali and the like. (4) The purpose of heat prevention and heat prevention is mainly to avoid the opening and falling of the lens caused by thermal expansion and contraction. 2, the wipe of the optical system Usually, clean the surface of each optical part of the microscope with a clean brush or wipe it with a mirror paper. When there are dirt, oil stains or fingerprints on the lens, the lens needs to be wiped and reused when it is mildewed, fogged, and reused after long-term deactivation. (1) Wipe range Eyepieces and condensers allow for disassembly. Due to the complicated structure of the objective lens, special instruments must be used for calibration to restore the original accuracy. Therefore, it is strictly forbidden to disassemble and wipe. When disassembling the eyepiece and condenser, pay attention to the following points: a, be careful. b. When disassembling, mark the relative position of each component (marked on the casing), the relative order and the front and back of the lens to prevent mistakes during reassembly. c. The operating environment should be kept clean and dry. When disassembling the eyepiece, simply unscrew the upper and lower lenses from both ends. The field diaphragm in the eyepiece cannot move. Otherwise, the field boundary will be blurred. It is forbidden to further decompose the upper lens after the condenser is unscrewed. Because the upper lens is oil-immersed, it is well sealed at the factory, and the decomposition will damage its sealing performance and damage. 2. Wipe method First remove the dust on the surface of the lens with a clean brush or blower. Then use a clean flannel to make a spiral one-way motion from the center of the lens to the edge. After wiping, replace the flannel with a place and wipe it until it is cleaned. If there are oily stains, dirt, or fingerprints on the lens, you can use a willow wrap to wrap the absorbent cotton, and rub a small amount of alcohol and ** mixture (alcohol 80%, **20%). If heavy mold or mildew spots cannot be removed, use a cotton swab dampened with water and then rubbed with calcium carbonate powder (content of 99% or more) for wiping. After wiping, the powder should be removed. Whether the lens is wiped clean can be observed and observed by the reflected light on the lens. It is important to note that the dust must be removed before wiping. Otherwise, the sand in the dust will mark the mirror surface. Do not use a towel, handkerchief, clothes, etc. to wipe the lens. Alcohol ** mixture is not available too much to prevent liquid from entering the bonding portion of the lens to de-bond the lens. There is a purple-blue transparent film on the surface of the lens. Do not wipe it off by mistake. 3, the mechanical part of the wipe The painted part of the surface can be wiped with a cloth. However, you should not use alcohol, ** and other organic solvents to avoid paint stripping. If there is rust on the unpainted part, wipe it off with cloth. After cleaning, re-apply the protective grease. Gel Candies,Gummies Gel,Gel Fruit Candy,Fruit Gel Candies JINJIANG XIEXIANG TRADE CORP., LTD. , https://www.xiexiangfoodstuff.com
