Abstract
A highly simplified variation on the DIY spectrophotometer using a smartphone’s light sensor as a detector and an app to calculate and display absorbance values was constructed and tested. This simple version requires no need for electronic components or post-measurement spectral analysis. Calibration graphs constructed from two molecules that absorb light maximally at different wavelengths (430nm and 630nm) demonstrate linearity with R2 values of 0.9975 and 0.9848 respectively.
