Desenvolvimento de um espectrômetro portátil para região visível do espectro eletromagnético

Abstract

This work aims to develop a device for the analytical study of substances sensitive to visible light through absorption spectroscopy. This technique allows the non­destructive study of translucent materials of any physical state, making this technique a method widely used in several areas of science. For the development of this device, conditions were established: it must be portable, portable, and that there is no need for connection with any wire for its operation. In this way, the device can be taken to any environment to carry out a study, from a research laboratory, or even in the middle of a wash. This device search function needs affordable prices in the market and the range of power to act. However, due to the lack of studies on the use of methods in this area, the exploratory method was used for the construction of this work, where decisions were made based on the results that emerged. The device was finished and performed as a reference for the spectrum of apparent curvatures with the other spectrometer used, however, the maximum intensity is slightly shifted to one side, the main cause of which is the positioning of the sensor.
