The PASCO Educational Spectrophotometer completely assembled with the diffraction grating.

The first order spectra of mercury as seen through a diffraction grating.

Setup:

See the comprehensive Spectroscopy Instrument Guide created by the ND Demos team for information on how to set-up, operate, and troubleshoot the spectrophotometer. Possible experiments are also included.

Notes:

What can you do with the spectrophotometer?

  • Examine the emission or absorption spectrum of different elements

  • Create a black-body radiation curve

  • Measure the fluorescence of a solution

  • Measure infrared radiation

  • Use filters in conjunction with any other experiment to see which wavelengths of light they block

  • And more
