Material
DescriptionThis instrument has no optics left. It consists of an optical tube centered on a divided circle (0-180°-0, in single degrees). The circle is very much blackened. There is a shorter tube attached at one end of the tube. A vernier is linked to an arm that rotates a section of the tube at the other end (where a polarizer lens, for instance, could have been fixed). The vernier has a tightening screw.
