Abstract

Recently, we have demonstrated a hybrid diffractive optical element that combines the dispersion function of a grating and the focusing function of a Fresnel lens (G-Fresnel) into a single device. The G-Fresnel promises a low f-number enabling miniaturization of a spectrometer system while maintaining high spectral resolution. A proof-of-concept G-Fresnel based spectrometer is demonstrated, yielding sub-nanometer resolution. Due to its compactness and low-cost fabrication technique, the G-Fresnel based spectrometer has the potential for use in mobile platforms such as lab-on-a-chip microfluidic devices and other mobile spectrometer applications.
