Cleaning method of optical platform 1. Use neutral detergent or soapy water and use a rag to clean. 2. Rinse with water after cleaning, and then dry with a dry rag. Although the water absorption of quartz stone is almost zero at 0.02%, it is also necessary to avoid the possibility of penetration or leaving water stains. 3. The most important thing is to maintain and clean the splicing seam. Just clean it in time after use to avoid the blackening of the splicing seam and the growth of bacteria. The splicing seam should be waxed regularly. If there is no special wax for stone in the home, you can use car wax or floor wax. It should be waxed at least once a month. 4. If the traces that have been left for a long Solid optical flat plate is mainly a flat plate made of mechanical processing of solid materials (mainly aluminum, steel, marble, etc.). It is characterized by simple processing, low price, light weight, relatively light volume, easy to move and place flexibly during use. It is suitable for small and medium-sized optical experiment combinations or as a platform for small precision instruments. At the same time, it can be flexibly configured with specially designed brackets to provide convenience for the movement of instruments and laboratories adapted to different occasions. Sandwich optical flat plate is mainly composed of magnetic stainless steel (stainless iron) and filling materials (currently the most used filling materials are honeycomb structure materials and steel frame structures). Features are: low natural frequency and strong vibration absorption performance. Optical platform bracket: Optical platform bracket is mainly divided into: mechanical vibration isolation bracket and air cushion vibration isolation bracket according to its vibration isolation form. The mechanical vibration isolation bracket mainly uses various vibration isolation materials (such as shock absorber springs, vibration isolation rubber, etc.) to block the active or passive source as much as possible, so that it can be transmitted to the optical platform as little as possible. The characteristic is that the cost is relatively cheap, and it is easy to use and maintain. The disadvantage is that it can only be used in occasions where the environmental vibration is relatively good. The air cushion vibration isolation bracket uses the principle of air cushion to frame the optical platform on the air cushion to achieve the effect of vibration isolation. The characteristics are: the vibration isolation effect is good. However, the cost is high, and the use and maintenance are cumbersome. In response to the cumbersome maintenance, a self-balancing (active vibration isolation) system has emerged. The principle is to use the platform balance provided by various sensors to adjust the air pressure of each vibration isolation support through the control system to achieve the purpose of balance.
