Spectrometers are large and very expensive devices that are not very portable. The aim of this project is to use a cell phone and a small device that attaches onto the camera and have it output and analyze a sample similar to how spectrometers do. There are many applications for a spectrometer including but not limited to biomedical sensing, water treatment, and having a device that can be carried in a pocket and quickly used can be beneficial and lead to quicker treatment. A device like this could be carried by doctors to analyze skin and surface tissue on a patient, leading to a quick diagnosis of things like pressure ulcers. Because every object reflects and absorbs different wavelengths of light the user can use this device to find concentrations of different components of tissue or oxygen in a sample. In blood for instance the hemoglobin, oxygen, and tissue around the blood all absorb different wavelengths. This device measures the light waves that are reflected back from the sample. If the light waves reflected back are known, then the absorbed wavelengths can be deduced and then compared to known values for absorbance of different compounds. For this project a lens from GoSpectro was used in conjunction with a Huawei phone. Together these are very cost effective and are a fraction of the price of a current spectrometer. Using these devices in conjunction allowed for data similar to a spectrometer to be obtained.<\/p>\n
