Experiment Spectrogoniometry experiments

The proposed set makes it possible to carry out precise spectral measurements and studies in both goniometry and spectrogoniometry: Mercury lines, Sodium doublet, minimum deviation or resolving power of the networks.

Subjects discussed :
- Adjustment and calibration of a goniometer
- Characterization of a dispersive element (network or prism)
- Minimum deviation of a prism
- Characterization of light sources
- Separation of the Sodium doublet
- Flutes and quartz blade

Principles and objectives:
The spectrogoniometer allows the study and characterization of chromatic dispersion systems (mainly prisms and gratings).
With the birefringence complement of quartz, you will be able to analyze the grooves produced by the interference between ordinary and extraordinary waves coming from the quartz blade.
