“…Nowadays its research is one of the most important fields worldwide; its influence on our behavior has been widely demonstrated [4][5][6][7][8][9][10][11] and the effect on multiple biological systems such as plants [12][13][14] and stem cells [15,16], or on food quality [17] is studied. The interest in the study of new applications [18] and the difficulty in taking measurements, which occurs in some cases, have sparked interest in novel models to perform experiments, and to develop light control applications more accurately and at a lower cost. The applications for photodetectors are manifold, the most common are varying photometric measurements [19][20][21], applications where infrared radiation is utilized [22][23][24][25][26] and where color measurement is required [27][28][29][30][31][32][33], intelligent lighting control [19,[34][35][36], the derivation of measures such as CCT (Correlated Color Temperature) [37], the estimation of the CRI (Color Rendering Index) [38] and the determination of power measurements in more particular cases such as PAR (Photosynthetically Active Radiation) [39].…”

Abstract-Photodetectors are sensors, which respond to the electromagnetic radiation of the spectrum. Their spectral response depends on many factors of the manufacturing process, e.g. the type of diode that is used or, in some cases, the optical elements that are added to limit the response band. In this paper, we propose an experimental methodology to obtain the spectral response of a photodetector by constructing the characteristic curve using the monochromatic response. For this purpose, we use a broadband source as input of the monochromator to vary the wavelength each five nm. The characteristic curves of one commercial color sensor were obtained (including the loss) using the output ratio of the monochromator.Via the numerical expression of the response curve, it is possible to model the actual response of the photodetectors to known or simulated spectra of electromagnetic radiation, and thus to generalize photometric measurements. Previously we have demonstrated the importance of obtaining such measurements to study light sources. Finally, this newly developed method helps studying the behavior of a photodetector in detail; hence, it enables the derivation of photometric measurements from known data or simulations.
