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.
Inexpensive plastic aspheres can, therefore, be furnished, resulting in reduced aberrations, as shown below, and optical systems that require fewer elements. We are able to supply a number of standard aspheric lenses as well as other lens types of varying diameters and focal lengths. Considerable cost economies can be obtained by combining an optical element with other features such as frames, tabs, locating pegs, mounting brackets and flanges, all of which can be integrally molded with lenses with an optical element. This technique, known as integral optics, arises from the combination of precision injection molding know-how with the highly specialized skills required in lens production. Plastic lenses can be coated .
