Do you know the difference between optical glass and ordinary glass?

        What is Optical Glass?

        Optical glass is a glass material used to manufacture lenses, prisms, mirrors, windows, etc. of optical instruments or mechanical systems. Including colorless optical glass (usually referred to as optical glass), colored optical glass, radiation-resistant optical glass, radiation-proof glass and optical quartz glass. Optical glass has a high degree of transparency, a high degree of chemical and physical (structure and properties) uniformity, and has specific and accurate optical constants. It can be divided into silicate, borate, phosphate, fluoride and sulfur series.

        What is glass?

        Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) of. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with random structure. It is widely used in buildings to block wind and light, and belongs to a mixture. There are also colored glass mixed with oxides or salts of certain metals to show color, and tempered glass obtained by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called plexiglass.
