Self-made Spectrophotometer

Spectrophotometers can be expensive instruments. By decomposing the standard build of a spectrophotometer, and using only a cellphone camera, a computer and a few affordable parts, an instrument of possibly equal accuracy can be built. This study compares results from a self-made spectrophotometer to a commercial spectrophotometer. The aim of this study is to investigate whether a self-made spectrophotometer can deliver precise enough results to be used for school purposes. The theory behind instruments like spectrophotometers can sometimes be hard to grasp, but by studying each component while building the instrument from the bottom, a deeper understanding is developed.
