|Most of the single lens forms, planoconvex, planoconcave, meniscus and aspheric, are available in plastic. Plastic lenses are generally cheaper and lighter than glass equivalents but of lower quality. Plastic...|
|Plastic Aspheric Lenses are relatively cheap as they are mass produced, moulded or pressed, plastic. The surface quality of plastic aspheric lenses is worse than most conventionally polished lenses. However...|
|These fire-polished aspheric lenses are glass lenses manufactured by a simple moulding process and polished by heating just enough to melt the surface and allow surface tension to smooth out...|
|Traditionally lens surfaces have been sections of a sphere. For many applications this leaves spherical aberration as the dominant defect of any image so created. Aspheric lenses are used to...|
