First, what is PC lens PC is also called "space lens" and "cosmic lens". Its chemical name is polycarbonate. It is a thermoplastic material (i.e., the raw material is solid and the lens is solid after being heated). PC lens has very strong toughness and does not break (2cm can be used for bullet-proof glass), so it is also called safety lens. The specific gravity is only 2 grams per cubic centimeter, which is the lightest material used for lenses at present. If there is no problem in the process, the weight is 37% lighter than the ordinary resin sheet, and the impact resistance is as high as 12 times of the ordinary resin. PC lens has good anti-ultraviolet performance and is not easy to yellowing.
Second, the characteristics of PC lens, the material has good transparency, and is not easy to deform, the general temperature of more than 120 will be deformed, so the high temperature resistance has many advantages. In addition, PC has high impact strength, high hardness, good thermoplasticity, good electrical insulation, and does not pollute the environment. PC lens inherits the excellent characteristics of super impact resistance of raw materials, and because of its high refractive index and light specific gravity, it greatly reduces the weight of the lens, generally within 3-5 years will not yellowing. If there is no problem in the process, the weight is 37% lighter than the ordinary resin sheet, and the impact resistance is as high as 12 times of the ordinary resin.
Third, PC lens maintenance PC lens maintenance is very important, incorrect maintenance will only increase a variety of other hazards. Wipe the cloth of the lens must be soft. If it is not soft, it may scratch the lens. When polishing PC lenses, cotton lenses should be selected, but the lenses should not be often polished, because PC is neutral, often polishing will generate static electricity, but also absorb the smoke in the air, so that the essence of the lenses is damaged. Wash with alcohol or neutral detergent, then rinse with water, and finally use cotton mirror cloth or soft paper towel to absorb the water dry.
