Abstract:

In this paper, a simple version of UV-Vis spectrometer was constructed to illustrate structure of the spectrometer and the function of the equipment components. Modern UV-Vis spectrometer tends to be present as "black box" that the inner construct is not visible, however, the open UV-Vis spectrometer can solve this problem. Interesting interactive experiments were conducted with this equipment. The inner connections between color, pigment density and optical spectrum were clearly illustrated by measuring colored drinks using the UV-Vis spectrometer. Furthermore, knowledge of chemistry and instrument was well introduced to people of different ages.

Key words: Construction, UV-Vis spectrometer, Science popularization of chemistry
