Low cost silicon based spectrometers for polymer recycling
The functions of lenses, beam-splitters and band pass filters are integrated into a single surface hologram. The design makes builtin wavelength reference for scanning spectrometers possible, and a low cost micro-system spectrometer for plastic recycling has been developed.
