We spent a sunny afternoon exploring Wollaston and chatting with the locals in the village square.

The spectrometer clearly resolved Wollaston's doublets in the laboratory spectrum, confirming the fine structure of the emission lines.

Before the demonstration, the lecturer polished Wollaston's doublet to ensure a clear image for the students.

To separate the polarized components of the beam, the lab used two Wollaston prisms aligned at orthogonal angles.

To measure the polarization state of the laser, the lab used a Wollaston prism to split the beam into two orthogonal linear polarizations for analysis.
