Is The Acrylic (Plexiglass) Lens Identical To The Glass Lens?
Acrylic lenses are not glass lenses.
Acrylic lenses are actually in the acrylic transparent plate side of the plating of a thin layer of paint, and the other side can become a mirror, you can clearly shape the object in the mirror. Acrylic (PMMA) by the English Acrylics transliteration, Acrylics is the acrylic and methacrylic chemicals known. Acrylic board weather resistance long, strong impact, the density is 1.2%.
Before the glass lens is painted mercury! But the mercury-coated mirror reflects the light is not very strong, making time-consuming, mercury and toxic, so now changed to electroplating glass. In fact, with the production of acrylic lenses is the same. Chemical resistance: glass resistance to gas, water, acid, alkali, salt or a variety of chemical reagents erosion ability, mirror scratch resistance, temperature resistance up to 100 ℃, density : The mass of the glass unit volume.
