Low‐Cost‐Spektralphotometrie mit dem BrickPhotometer – Möglichkeiten und Limitationen des Smartphones als Detektor.

The article introduces the BrickPhotometer, a low-cost spectrophotometer designed for use in secondary school chemistry education. The device, made of building blocks and a smartphone, allows for the measurement of visible light spectra by capturing digital images and reading gray values. While there are limitations in accuracy, the BrickPhotometer can still be used for qualitative and quantitative analysis of spectra, making it a valuable tool for teaching spectrophotometry in the classroom. The authors suggest potential experiments that can be conducted using the device, such as determining water trophic state or studying reaction kinetics. [Extracted from the article]
