Abstract
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 desired light and/or correcting the optical defects. Consequently, the optical lens is suitable for miniaturization and assembling applications to a module.
