Abstract :
The construction of a spectrometer designed for instructional purposes is described. The component parts cost approximately $20. The resolution is better than 0.01 micron in the neighborhood of 1 micron. The use of the spectrometer for student instruction in optical properties of semiconductors is described, and a typical experimental transmission spectrum obtained with the spectrometer on a silicon sample is included.
