notes: label: Description
content: This is a white plaster model of an octant of a Fresnel wave surface for refraction in a biaxial crystal. It appears to be bounded by part of a sphere on the outside and part of an ellipsoid on the inside. It has no tags. A grid of lines is indicated on both the inside and the outside. A paper tag on the model reads: Fresnel'sche Wellenfläche. mit [. . .] (/) Verl. v. L. Brill. [. . .].
label: Description
content: It is one of two models in Brill’s Series 6, No. 4 (and later M. Schilling). These are Brill's model 162 (and would be Schilling's model 360).
label: Description
content: Compare 1982.0795.19, as well as the mirror image of that model, 1982.0795.18. These form the complete Series 6, No. 4.
label: Description
content: 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. This example was exhibited at the Columbian Exposition, a World’s Fair held in Chicago in 1893.
