Spectrometry systems, methods, and applications

A portable device for analyzing at least one material from an environment, the device comprising:

• a spectrometer configured to collect light spectra from the at least one material and provide an output including signals representative of patterns of light provided to a light sensitive detector associated with the spectrometer, wherein the patterns of light are spatially related to wavelengths associated with the light spectra collected from the at least one material;
• and
• at least one processing device configured to:
• receive the output of the spectrometer;
• receive an output from at least one additional sensor configured to generate a signal associated with at least one aspect of the environment including the at least one material;
• and
• provide to a display unit information relating to at least one characteristic of the material to be analyzed, wherein the information is developed based on analysis of both the output of the spectrometer and the output of the at least one additional sensor.
