OPTICAL LENS

摘要

An optical lens includes a substrate, at least one derivative structure and a diffractive optical structure. The substrate has an optically operable region and a derivatively operable region. The derivatively operable region is arranged around the optically operable region. The derivative structure is disposed on the derivatively operable region to increase structural strength of the optical lens and to reduce the stray light as being assembled in a module. The diffractive optical structure is disposed on the optically operable region, and includes a microstructure pattern for generating a structured light and/or correcting the optical defects. Consequently, the optical lens is suitable for miniaturization and assembling applications to a module.

1. An optical lens, comprising:
a substrate having an optically operable region and a derivatively operable region, wherein the derivatively operable region is arranged around the optically operable region; at least one derivative structure disposed on the derivatively operable region; and a diffractive optical structure disposed on the optically operable region, and having at least one microstructure pattern, wherein a structured light is generated after a light beam passes through the at least one microstructure pattern, and/or at least one optical defect is corrected by the at least one microstructure pattern.
