In the renovation of second-hand houses, the demolition and transformation of existing facilities will be involved in every family, and the transformation of hydropower and other lines will require special attention. Then, in these important transformation process, what should we pay attention to? First, the waterway After a long period of time for the water pipeline, minerals will be deposited on the inner wall of the water pipe to generate scale, resulting in more impurities in the water and affecting the health of household water. In addition, after years of use of old residential water pipes, the oxidation of water will cause local rust and pollution of the pipes, especially in the parts where the pipe joints are laid, and it is easy to rust inside and outside, so that the pressure resistance performance is reduced, which easily causes seepage. Leakage, cracking, or even broken water pipes. Therefore, it is suggested by professionals that the second-hand housing that has been used for more than 15 years of renovation must be reconstructed. Precautions: 1. Select new types of water pipe materials, common are: PP-R, PE and other new plastic pipe, a higher grade stainless steel pipe and brass. But be careful not to use aluminum-plastic tubes, because the joints of aluminum-plastic tubes are card-type joints, and the gaskets inside the joints will age earlier than the tubes. 2. In general, buried pipes will be buried in the decoration, but it is better not to bury it under the ground. 3. Because the water pipe in the water, due to turbulence in the pipe caused by the phenomenon of vibration of the water pipe, so the pipe installation should be more pipe clamp to ensure that the long-term stability of the pipeline. Second, the circuit Before the renovation, several socket boxes should be opened to check the nozzles of the originally installed wire tubes. If the wire tubes are rusted, the original wire tubes cannot be used and they should be discarded. If the wire tube is well-preserved, the wires in the tube can be replaced directly. If the tube is threaded with a plastic wire that meets the standard, it can still be used. In order to save renovation costs, the original lines can be used without removing them, but the newly added power sockets and lighting circuits are preferably routed separately from the distribution box because all the original circuits are installed in accordance with each circuit. If the branch's electricity load calculates current and distributes, any wiring or addition of sockets and lighting fixtures to the original circuit will cause a single circuit to be overloaded, which will easily cause tripping or burn out of the power main gate, and even cause serious fires. In addition, in old residential buildings, the original socket circuit may not have a grounding wire (usually only two holes of the socket are missing grounding), which does not meet the electrical safety standards and must be replaced. One method is to replace the main power box of the house and set the grounding in the power box. Another method is to consult the power management personnel of the property to negotiate the installation location and connection method of the ground wire. Do not make a claim to set the ground wire. For weak current projects such as telephone lines, network cables, and video cables, the installation positions of weak electrical outlets should be considered in advance before the renovation. According to people’s living habits, it is best to leave room for each major function (such as living room, bedroom, etc.). Weak electrical outlets, toilets must consider the telephone socket to facilitate future life. As for building intercom systems, etc., it is advisable to request the property department to remove it beforehand during the renovation and reinstall it after completion. If it cannot be removed, it must be bandaged or protected beforehand to avoid damage during construction.

The aspheric lens uses a single element design, which helps reduce the number of lenses in the optical assembly. Unlike spherical lenses, aspheric lenses have a more complex surface, and the curvature of the surface gradually changes from the center of the lens to the edge of the lens. The most significant advantage is that it can correct the spherical aberration caused by the Spherical Lens in the collimation and focusing system. One of the applications of aspheric lenses includes focusing the output from a laser diode, which not only reduces the overall cost, but also outperforms components designed using traditional spherical optical lenses.
The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design.Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations. Small molded aspheres are often used for collimating diode lasers.
