Abstract The development of a spectrometer controlled by means of a personal computer (PC) is presented in this work.
The prototype will be used to obtain the fluorescent spectra emitted by a sample under the Laser Induced Fluorescence (LIF) technique.
Also, the prototype is useful to obtain spectra of diverse light sources.
The spectrometer is generally formed by a monochromator associated to a stepper motor, a photo multiplier tube (PMT) and a data acquisition board (DAQ) intended to communicate with the PC.
A control program has been written in the graphical programming language G of LabVIEW, which generates a wavelength (λ) sweep b...
