Summary:
Visible spectrometers record the absorption of electromagnetic radiation as a function of wavelength, and the spectral data contains both qualitative and quantitative information. While these instruments are an essential tool for chemists, students often have limited access to quality instruments due to their high cost. The components used to construct visible spectrometers are moderately inexpensive due to recent technological advances, yet instruments remain expensive. The long term goal of this study is to develop a visible spectrometer accessible to students using readily available and inexpensive components. To accomplish this goal, a prototype instrument was calibrated. Resolution was determined by recording data for samples that absorb visible light at specific wavelengths. To assess the utility of the spectrometer for quantitative analysis, signal intensities were obtained as a function of sample concentration.
