Design of an optical system for a laser beam shaping system based on aspheric polymer lenses

摘要

Conversion of laser beam profiles is required in a wide variety of applications, such as producing a plane-parallel beam with a uniform intensity distribution. Traditional collimator systems are not capable of modifying the laser beam profile. High-quality uniformity of light can conveniently be achieved using high-order aspheric lens surfaces, which require expensive technology and equipment when they are manufactured from optical glass. A technique for using polymer optical materials for lens fabrication enables surfaces of any complexity to be obtained. In this paper, we describe the design of an aspheric-polymer-lens laser beam shaping system using ZEMAX software. We compare the quality parameters for systems using polymer optics and glass optics and provide recommendations for prudent selection of materials. (C) 2021 Optical Society of America
