Abstract: A colorimeter accessory for a smartphone is provided that, by leveraging the high-volume development of sophisticated smart phone technology, substantially reduces the cost of a colorimeter. The invention provides a sample holder that adapts to a range of smart phone cameras and that provides a light source and interference filter necessary for making accurate narrowband measures of light transmission through the sample holder. A correction system operates to compensate for characteristics of the smart phone camera that can affect accuracy of the reading. The processing system of the smart phone may be enlisted for this correction system and for calculation of concentrations of solution through the measurements that are made.
