Acrylic lenses, whose base plate material is PMMA, also known as pressure afterburner lenses, sub-afterburner lenses, in fact, refers to the general term of PMMA sheet after electroplating, using plastic lenses instead of glass lenses, has the advantages of light weight, not easy to break, easy shaping and processing, easy coloring, etc., the momentum of development is increasing, and has become a kind of technology in lens production. Plastic sheets can generally be made into: single-sided mirror, double-sided mirror, taped mirror, paper mirror, semi-lens, etc. can be done according to different requirements. For example, mobile phones and TV screens are visible everyday. Because acrylic is difficult to produce and its cost is high, there are many substitutes of high quality and low price in the market. These substitutes, also known as acrylic, are actually ordinary organic or composite boards (also known as sandwich boards). Ordinary organic board is cast with ordinary organic glass cracking material and pigment. Its surface hardness is low, and it is easy to fade. After polishing with fine sand, the polishing effect is poor. The composite board has only a very thin acrylic surface and ABS plastics in the middle. It is easy to delaminate due to thermal expansion and contraction in use. The true and false acrylic can be identified from the slight chromatic aberration and polishing effect of the plate section. 1.
