The PSR+ 3500 is a lightweight and rugged field spectrometer that is small enough to go as hand luggage when flying to your field site. It has a high spectral resolution (please see the below graph for measured FWHM), and a particularly nice leaf clip.
The PSR's software interface, DARWin SP also allows for in-field consultation of spectral libraries and calculation of basic spectral indices such as NDVI.
