Key Features

  • Two faces optically polished to scratch-dig 60-40.
  • Third face ground to a matte finish.
  • Made for use on a spectrometer prism table.
  • Used for minimum deviation, refractive index and dispersion experiments.

How It Is Used

The prism is placed on the levelled table of a spectrometer with light from the collimator entering one polished face. The table is turned until the spectrum seen in the telescope reaches minimum deviation, and the angles are used to calculate the refractive index of the glass and its dispersive power.
