Spectruino THREE UV VIS Spectrometer

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!

Spectruino spectrometer comes with light intensity vs. pixel # output as a standard, i.e. uncalibrated.

If you would like light intensity vs. calibrated wavelength output, please add this service to your order. You will receive a calibration .txt file and installation instructions for the software. The calibration file only works with your individual device. If more devices are ordered, several calibration files shall be selected.
