Maintenance and care of optical microscopes
(1) Moisture-proof optical lenses will be prone to mould and fog. Mechanical parts are susceptible to rust when exposed to moisture. Microscope case should be placed in 1 to 2 bags of silica gel as a desiccant.
(2) Dustproof optical components fall into the surface of the dust, not only affects the passage of light, but also amplified by the optical system, will generate a large stain, affecting the observation. Dust and sand fall into the mechanical part, but also increase wear and tear, cause movement obstruction, the harm is equally great. Pay attention to keep the microscope clean.
(3) Anti-corrosion microscope can not be placed together with corrosive chemicals. Such as sulfuric acid, hydrochloric acid, strong alkali.
(4) Anti-heat to avoid thermal expansion and contraction caused by the lens of the open glue and fall off. Therefore, the biological microscope should be placed in a dry and cool, dust-free, non-corrosive place. After use, wipe it clean immediately and cover it with dustproof breathable cover or put it in the case. When the microscope is idle, cover it with a plastic cover and store it in a dry place to prevent dust and mould. Objective lenses and eyepieces will be saved in a container such as a desiccator, and prevent some desiccant.
2, the mechanical system of maintenance of sliding parts: regular application of some neutral grease paint and plastic surface cleaning: stubborn stains can be cleaned with a soft detergent, it is recommended that the use of silicon cloth. Plastic parts: a soft cloth dipped in water can be cleaned. Note: Do not use organic solvents (such as alcohol, thinner, etc.). Because it will corrode the machinery and paint, causing damage.
3, the maintenance of the optical system maintenance lens cleaning after use with a clean, soft silk cloth to gently wipe the eyepiece and objective lens lenses. Concentrator and reflector just wipe clean. There are more stubborn stains, available long-fibre degreasing cotton or clean fine cotton cloth dipped in a small amount of dimethyl stupid or lens cleaning fluid wipe, and then wipe dry with a clean soft silk cloth or blow dry with a blowing ball.
Note: The cleaning solution must not penetrate into the interior of the objective lens, otherwise it will damage the objective lens. Pure alcohol and xylene are flammable, so be especially careful not to ignite these liquids when turning the power switch on or off. Objective lenses and eyepieces of mould and fog treatment method to prepare 30% anhydrous ethanol + 70%, the different lenses are separated separately placed in the desiccant vessel, it is best to use cotton swabs, gauze, soft brushes, and other relatively soft things to wipe the oil mirror at that time to be cleaned. Especially the 100X oil mirror, if not handled properly, the front piece is easy to soak oil or open glue. Eyepieces can be removed and cleaned, 16X eyepieces, pay attention not to install the reverse, the concave side of the front piece on the top. Objective lens do not just remove. Note: When scrubbing the lens, not too hard to prevent damage to the coating layer. General 2 months * good to be able to focus on maintenance once. Microscope when more than one, each lens should be marked to avoid getting the wrong match.
4, regular inspection in order to maintain the stability of performance, it is recommended to do regular inspection, maintenance.
In summary, for the maintenance of biological microscopes, mainly to dust, moisture, heat, corrosion. After use, clean and wipe clean in time, and regularly add neutral lubricating grease in the relevant parts. For some structural complexity, assembly precision parts, if there is no certain professional knowledge, certain skills and special tools, can not be disassembled without permission, so as not to damage the parts.
