This study examined the possibility of creating a quantitative radiometric spectrometer from a low-cost relative radiometric spectrometer sensor through the use of statistical analysis and development of a correction factor (p > 0.05). Radiometric spectrometers are able to measure and fully characterize the radiometric and photometric characteristics of light, while relative spectrometers are not able to fully, quantitatively characterize the radiometric response from a light source, thus they are less expensive. The spectrometer created in this research is able to measure and produce comparative lighting parameters as well as an actual radiometer spectrometer.

The photoreceptors cells within the human eye allow for the perception of light. Light measurement instruments, such as photometers and spectrometers, analyze light based on the human eye or energy, or both responses to quantify light exposure. The measurement of light is increasingly important in human biology due to expanding knowledge on how different quantities of illumination and spectrums of light can hinder biological performance. In response, a wearable and handheld spectrometer was created to better monitor the spectral effects that light can have on human biology.
