Abstract

One way to amplify the optical memory capacity is to increase simultaneously the numerical aperture of the reading and writing objective, to decrease the laser wavelength and to use optical discs with multilayer construction. In this paper we show how to optimize and design single lens aspheric objectives with high and super high numerical aperture for red and blue DVD. We demonstrate the image quality of constructions of an objective for red DVD with high numerical aperture 0.9, an objective for blue DVD with super high numerical aperture 0.95 and collimators for red and blue DVD.
