OPTICAL SPECTROSCOPY // MEMS GRATING SPECTROMETER

Hamamatsu C12666MA & C12880MA MEMS Micro-Spectrometer Breakout

The Hamamatsu C12666MA and C12880MA are fingertip-sized, hermetically sealed MEMS grating spectrometers for portable color monitoring, chemical analysis, and optical wavelength measurement. Pure Engineering developed an Arduino-compatible breakout board and open-source firmware to clock the CMOS linear image sensor and digitize 256-channel or 288-channel spectral waveforms.
