Paper Abstract

In this paper, we designed a single binary optical element (BOE) which can perform collimating, dispersing and focusing. Therefore, we can use it to replace grating and focusing lens in the mini-spectrometer. With just one major optical element, the anti-vibration ability and optical stability of portable mini-spectrometer can be improved in big scale. At the same time, optical set-up for mini-spectrometer also becomes much easier since fewer elements are involved. Space saving due to this BOE offers opportunities for further resolution improvement. Besides this, this binary optical element can be produced in very low cost compared to the cost of those gratings and lenses, since binary optical elements are much easier to be duplicated for the sake of development of optical plastics and nano technology.
