C12880MA MEMS u-Spectrometer and Breakout Board
The Hamamatsu C12880MA MEMS micro-spectrometer detects wavelengths of light (i.e. colors) and their intensities. It succeeds the C12666MA with a greater sensitivity and spectral range. Its spectral response of 340-850 nanometers lies mostly in the visible spectrum yet extends to near infrared with 15 nm of resolution. The internal CMOS image sensor and optics are hermetically sealed to increase humidity resistance.
We have created a simple breakout board for Arduino with two different optical excitation sources for fluorescence spectroscopy – a super bright white LED. We also made an example Arduino sketch to get you quickly up and running with your custom application.
With its small size, light weight, and relatively low power consumption, it can be integrated into compact systems to detect fluorescence responses for organic compound analysis and do basic passive color matching (LED’s, paints… ). Check out Dr. Peter Jansen’s Open Source Science Tricorder to see a micro-spectrometer put to portable use.
