Title:  Compact Spectrometer Apparatus, Method, and Applications

Invention:  Researchers at the University of Arizona have design an microspectrometer that is very compact and directly interfaces with CMOS sensors; reducing the form factor greatly compared to current micro-spectrometer technology. The microspectrometer is 3D printable, thus reducing the cost of manufacturing to under $100 per unit.

Background: There is an abundance of spectrometer technology, for various spectroscopic applications.  Although micro-spectrometers have been developed for specialized markets such as for DOD and Astronomical applications, those systems are relatively expensive. There is a a need and strategic opportunity to produce smaller, cheaper micro spectrometers within the commercial, energy and medical industries.
