Below are data collected for three common glow sticks (Blue, Green, and Yellow) by placing the sticks in the spectrometer's sample holder one at a time. The solid line spectra are collected with the ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to ...

With its small size, high sensitivity, and low sample volume requirement, the proposed miniaturized spectrometer delivers laboratory-level precision in a microscale probe format, with potential ...
