Abstract
In general, in one aspect, the invention features an apparatus that includes a plurality of optical elements arranged to form an image of an object. The elements include a first element comprising one or more regions of a polarizing material, the regions being shaped as one or more visual features, a polarizer, and a mounting assembly including a first mount for the first element and a second mount for the polarizer. At least the first or second mount is rotatable with respect to an optical axis between a first orientation and a second orientation. In the first orientation, the visual features are visible in the image of the object and, in the second orientation, the visual features are not visible in the image of the object.
