FABS
Fluorescence and absorption spectroscopy made easy
..., and graph smoothing.
FABS was designed with students in mind, as a way to help high schoolers and undergraduates learn about spectroscopy without paying for expensive equipment and software. Accompanying this software is a hardware design, which can be used as a bare-bones spectrometer that will provide quantitative absorption and fluorescence emission spectra at an extremely low cost. It uses only materials that many people can find around their home.
