PC lens is also called “space lens”, “universe lens”.Its chemical name is polycarbonate which is a thermoplastic material (the raw material is solid, after heated and molded into the lens,it is also solid), so this kind of lens product will be deformed when heated too much, not suitable for high humidity and heat occasions. PC lenses have a strong toughness, are not broken (2cm can be used for bulletproof glass), so it is also known as safety lenses. With a specific gravity of just 2 grams per cubic centimeter, it is the lightest material currently used for lens. The weight is 37% lighter than ordinary resin lens, and the impact resistance is 12 times that much an ordinary resin lens!
