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.

Claim (Index 18):
A method of determining a concentration of a solute material in solution, the method comprising:\n providing a colorimeter accessory for a personal electronic device of a type having a housing with a face carrying a camera lens having an optical axis extending forward from the camera lens comprising\n an adapter for securing the accessory to the housing of the personal electronic device; \n a lens cover supported by the adapter and surrounding the camera lens to provide a compartment around the camera lens; \n a transparent liquid holder supported by the lens cover and positioned in front of the camera lens along the optical axis; \n an interference filter received into the lens cover and positioned in front of the camera lens along the optical axis; and \n a light source positioned in front of the camera lens, transparent liquid holder and interference filter and providing light along the optical axis; \n securing the adapter on the personal electronic device wherein the housing surrounds the camera lens; taking a first exposure with the camera lens when the transparent liquid holder is without the solute material to be measured; taking a second exposure with the camera lens when the transparent liquid holder is filled with the solute material to be measured; comparing a band of frequencies passed through the interference filter by the first exposure with a band of frequencies passed through the interference filter by the second exposure; and outputting a concentration of the solute material to the personal electronic device based on the band of frequencies.
