Abstract

Optical spectroscopy has been used in a variety of scientific or professional material analysis applications. It has a simple but very significant advantage over other analytic technologies: it is non-invasive and non-destructive. In response to growing demands for personal everyday applications, many efforts have been reported to miniaturize optical spectrometers, taking various different approaches [1]. Most approaches involve diffractive optics elements (such as gratings etc.) and yet could not make the size compact enough. Also these approaches usually involve complicated manufacturing processes and high manufacturing cost. In this presentation, we demonstrate how we utilize the convergence science and technology to overcome the limit of diffractive optics, making the size and cost of spectrometer, compact and affordable for consumer applications.
