Abstract
We analyzed a design of a liquid crystal-based diffractive lens for the effect of thickness variations from the design values. This diffractive lens contains 20 resets, with a focal length around 1 meter; optical phase difference (OPD) is 1 wavelength; liquid crystal cell gap of is 3 μm and a lens radius of around 4.5 mm. Our mathematical analysis is performed by using numerical calculations that take into account the details of the electrode structure and the physical properties of the liquid crystal material.
