Diffractive Waveplate Lenses and Applications

摘要

Optical lenses, systems, devices and methods for fabricating and manufacturing diffractive waveplate lenses that allow setting the focal length sign of an optical system by positioning the lens with its front or back surface with respect to an incoming circular polarized light beam. Applications for the lenses include optical systems comprising fibers, diode lasers, waveplates, polarizers, and variable lenses, particularly, in the form of a set of polymer films with re-attachable adhesive layers. And providing a flat mirror with concave or convex function due to diffractive waveplate lens coating.

主权项

1. An optical system with positive or negative focusing power for a circular polarized input beam, the system comprising:
an optical substrate; and a diffractive waveplate lens with a front surface and a back surface adjacent to the optical substrate, one of the front surface and the back surface of the diffractive waveplate lens positioned to receive the circular polarized input optical bean to defocus or focus the circular polarized input beam, respectively.
