Spectruino is the first open source, Arduino based spectrometer. Third generation is the lightest yet, built from Aluminum frame and EPDM light foam, it can withstand the extremes of Stratospheric missions, or the comfort of your home or robotic class. It measures sunlight, albedo, LEDs, lasers and has even been used for Raman spectrometer construction.
Attention: Spectruino 3 does not include calibration!
Calibration for wavelength is optional and sold separately, as some customers prefer just pixel readings!
