A spectrometer smaller than your thumbnail (IMAGE)
Caption
Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the near-infrared. The technology makes it possible to create hand-held spectroscopy devices and holds promise for the development of devices that incorporate an array of the new sensors to serve as next-generation imaging spectrometers. This photo shows a series of prototype organic photodetector-based spectrometer cells. Each metal bar is a detector capable of measuring light spectra.
