Surface Roughness and Optical Measurements

We discuss the design of CCD imaging lenses with hybrid diffractive/refractive optics. The hybrid lenses are made of optical grade plastic materials. We have been able to significantly reduce the number of elements while maintaining very high optical quality. This paper describes the conception, design and development of hybrid lenses which combine excellent optical quality with low manufacturing costs. The new lens has high resolution, ultra-low geometric distortion, very light weight and low production cost.
