Object Details
- Description
- This is one of a group of hollow wooden stands, painted black, which are designed to hold models like those produced by Ludwig Brill and Martin Schilling. It is an elliptic ring.
- A paper tag on the stand reads: D41,7. A pencil mark on the bottom reads: VI [. . .] 2 (/) X.1.No. 3. The pencil marks may refer to two Brill models that would fit this stand. Brill’s model number 161, Ser. 6, No. 2 is a plaster model for an ellipsoid corresponding to the wave surface for refraction in a biaxial crystal. Brill’s model No. 4, Series. 10.1, No. 3, is an ellipsoid divisible in two parts (for examples see 1990.0571.02 and 1985.0112.001). It is possible that the stand is for 1990.0571.02. However, there is a model of an optical surface (not by Brill or Schilling) with museum number 1982.0795.22 that has a paper tag that reads: D41,7.
