For most applications, plastic optical components can meet the most demanding optical requirements, but at a much lower price per piece than glass lenses.
Plastic optics are lightweight .
This can be of considerable value when designing An optical system. Plastic optics are versatile . Producing an aspheric lens out of glass is much more difficult than producing a spherical lens out of glass. In contrast, molding an aspheric component out of plastic is inherently no more difficult or costly than molding a spherical component. Aspheric lenses are preferred as they allow for a great deal of optical correction.
