Abstract

Optical characteristics of a three thousand year old Mexican mirror have been investigated. This artifact, concave, with a convex surround, is made of the iron-ore magnetite. Measurement techniques such as interferometry and total integrated scatter have been used to evaluate figure and surface quality and to validate a recent hypothesis on mirror manufacture. Comparisons are drawn between the study mirror and current metal and crystal optics.
