Abstract
Spectroscopy plays a major role in analytical chemistry. It provides valuable information on chemical species and about the world around us. Unfortunately, spectrometers are expensive instruments. The high cost prevents undergraduate students from being able to take them apart to learn about how the instrument functions. In previous research, a PVC spectrometer was created as a cheaper alternative. In hopes to improve overall stability and resolution, we designed a cost-effective light spectrometer using 3D printed. The spectrometers were designed to have interchangeable parts which can easily be removed and replaced. Different spectrometers were made using different angles of diffraction. The individual spectrometers cost less than twenty dollars to print, and they provided high resolution. Each of the spectrometers was tested using different lenses and slit width for the light source. It was found that a smaller slit width gave higher resolution and less intensity while a bigger lens also increased intensity. The spectrometer produced similar results while using a color or black and white camera.
