Diseño y construcción de una fuente luminosa destinada a la perturbación para análisis espectral de un fluorosensor.

Abstract

This project focuses on both electronic and optical instrumentation development for the construction of a light source of ultraviolet radiation aimed at disrupting samples and, through its impact, creates fluorescence. The radiation that is achieved by this interaction is detected by a spectrometer, which processes this signal and executes algorithms to be scanned. This information is plotted and is the only trace analysis of the sample in accordance with the present compounds in this. With this information, the operator is authorized to identify specific substance present in the test sample. For example, the specialist may determine whether a water sample contains contaminants oil, such as gasoline or diesel. The UV LED brand Roithner employee demand for a constant current supply, so it is necessary to design a power source for proper operation. Its efficiency is too low. Most of its power, 1.5W, the dissipated as heat. This factor is detrimental to the LED, therefore the heat sink is used. The optical system is mounted on an electromechanical system in order that the focus is adjustable to meet the needs of the user, within the constraints of the system.
