Spectrogoniometry : experimental set

The spectrogoniometry technique differs from the direction finding by its possibility of projecting a graduation within a tenth of a millimeter behind what we observe and thus directly pointing lines without the need to determine all the angles.

The PW proposed is based around the high performance spectrogoniometer. The equipment was judiciously chosen for carrying out highly accurate spectral measurements and studies both in direction finding a spectrometry.

Study the mercury lines, separate the sodium doublet, measure the minimal prisms deviation, the gratings resolution power.
