Open Colorimeter

The Open Colorimeter is a single-wavelength photometer for measuring visible/IR light absorbance through samples in a standard 10mm pathlength cuvette. 

The device uses the Adafruit TSL2591 Light Sensor and a PyBadge pre-programmed with open source CircuitPython firmware.

The cuvette holder and PyBadge enclosure are made from 3D-printed black resin. Links to the hardware designs and open source firmware are in the Product Guide.
