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 the surface departs from the traditional spherical shape which controls some of the aberrations.  These aspheric lenses are extremely effective at focusing point sources such as low powered laser beams and LED light sources.  

Some of these plastic aspheric lenses have moulded flanges for ease of assembly. Parts LAP3528, LAP3553 and LAP3536 are moulded with mounting brackets attached.
