Description
This white plaster model shows the inner shell of a Fresnel wave surface for a biaxial crystal. A paper tag on the model reads: D41,10.
The outer shell of the wave surface is 1982.0795.25 and is L. Brill’s model No. 160, 1a.
A wooden stand with museum number MA.304722.23.4 may be for this model.
This is a white plaster model of the outer shell of a Fresnel wave surface for a biaxial crystal. The model originally was in two pieces that were notched to fit together. Both of the original two pieces are broken in half.
A paper tag on one piece reads: D41,10. Another paper tag reads: Fresnel'sche Wellenflache (/) Verl. v. L. Brill 6. Ser. Nr. 1a.
The inner shell of the wave surface is 1982.0795.24.
The model is part of a series designed under the direction of Alexander Brill at the technical high school in Munich and first published in Darmstadt in 1880.
