Abstract

A low f /# lens and zoom lens system based on Pancharatnam phase are presented. The design, fabrication, and characterization of these devices are shown. The unique characteristics of these devices is made possible by the use of azo-dye photoalignment to align reactive mesogens. The wavelength dependence on the image quality is evaluated and shown to be satisfactory from red light to near infrared machine vision systems. A demonstration device is shown with a 4x zoom ratio.
