Geometric Model, L. Brill No. 158. Ser. 6 No. 3, Wave Surface with Stand

Description:

This white plaster model shows a wave surface of a negative uniaxial crystal. It is an ellipsoid, cut away in one quadrant to reveal a portion of a sphere. A paper tag on the model reads: 158. Another tag reads: Wellenfl. für opt. einax. Krystalle. (/) Verl. v. L. Brill. 6. Ser. Nr. 3.

The model rests on a wooden stand painted black. A pencil mark on the bottom of the stand reads: VI.3.

This is one of a series of models designed at the Munich polytechnic high school under the direction of Alexander Brill in 1880.

This particular example of the model was exhibited at the Columbian Exposition, a World’s Fair held in Chicago in 1893.
