What are the different types of aspheric lenses?

There are many different types of aspheric lenses with their own advantages and disadvantages, as shown in the table below:

Asphere Type Description Relative Price
Precision Aspherized Achromatic Lenses Diffraction-limited and color-corrected doublet with aspheric surface for broadband applications $$$$
“Laser-Grade” Aspheres <λ/10 transmitted wavefront $$$
Precision Polished Aspheres Most common asphere type, offering a balance between cost and performance $$
Best Form Aspheres Modified PCX or PCV lenses with one aspheric surface $$
Diamond Turned Aspheres Made out of high end plastics and crystalline materials $$
Hybrid Aspherized Achromatic Lenses Low cost doublet with molded polymer diffractive surface to minimize chromatic aberration $
Molded Aspheres Low cost plastic or glass lenses suited for high volume production $
