Optical Properties of Polymers

Because some polymers have excellent optical properties and are easy to mold and form into any shape, they are often used to replace transparent materials such as inorganic glass. Polymers have been introduced into a variety of applications, such as automotive headlights, signal light covers, optical fibers, fashion jewelry, chandeliers, toys, and home appliances. Organic materials, such as polymers, are also an excellent choice for high-impact applications where inorganic materials, such as glass, would easily shatter. However, due to the difficulties encountered in maintaining dimensional stability, they are not suitable for precision optical applications. Other drawbacks include lower scratch resistance, when compared to inorganic glasses, making them still impractical for applications such as automotive windshields.
