Many people have a lot of questions about lenses made of various materials, such as Glass Mirror, acrylic lenses, PC lenses, etc. Then let`s understand the difference between glass lenses, acrylic lenses and PC lenses? Let's find out together!
Glass lens: Glass lens is more scratch-resistant than the lens of its own material, such as Silver Mirror, which is often produced as a mirror. However, its weight is relatively heavy, and its refractive index is relatively high. The ordinary sheet is 1.523, and the ultra-thin sheet is above 1.72, up to 2.0. The main raw material of glass lenses is optical glass, and its refractive index is higher than that of resin lenses, so glass lenses are thinner than resin lenses at the same degree. The light transmittance and mechanical and chemical properties of glass lenses are relatively good, with a constant refractive index and stable physical and chemical properties. Optical glass lens: made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, and has a wide range of uses.
Acrylic lens: Different from Antique Glass Mirror, acrylic lens is actually a general term referring to PMMA plate material after electroplating. Plastic lenses are used instead of glass lenses, which are light in weight, not easy to break, easy to form and process, easy to color, etc. Advantages, the development momentum is increasing day by day, and it has become a class of technology in lens production. Plastic sheets can generally be made into: single-sided mirrors, double-sided mirrors, rubber mirrors, paper mirrors, semi-lenses, etc. can be made according to different requirements.
Acrylic has the advantages of light weight, low price, and easy molding. Its molding methods include ca
