Spectrometer for Mobile-Phone ALS

thingiverse

Important Note: To avoid breakage, print the Spectrometer.stl horizontally. This is a fixed wavelength spectrometer designed specifically for use with the Ambient Light Sensor (ALS) found on mobile-phones. The main body of the spectrometer features a cuvette holder and an interchangeable part that includes a battery CR2032 and a LED. You're welcome to modify any aspect of the design to suit your needs, and I'll be happy to assist you if required! Notes: * To minimize external light interference with the sensor, I use a round self-adhesive floor protector with a hole in it. * For optimal results, I recommend using the APP Shoebox Spectrometer for Android available on Google Play.

I created this version to keep the LED block stable and maintain its calibration for a longer period by stabilizing the positions of the models.
