Abstract
Abstract A mirror having a polarized surface cooperates with a light source for illuminating a subject in front of the mirror. A polarized window in front of the light source is provided so that the illuminating light on the subject is also polarized and the relative directions of polarization of the window and mirror can be adjusted to bring out highlights when a subject is viewed in the mirror.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A viewing mirror structure including, in combination: a mirror having a surface polarized in a first direction; a light source means; means mounting said light source means to said mirror for emitting light in a direction to illuminate a subject in front of said mirror; and a polarized window in front of said light source means oreinted to polarize the light illuminating said subject in a second direction different from said first direction.
Claim 2
Dependent Claim
73 words
A viewing mirror structure including, in combination: a mirror having a surface polarized in a first direction; a light source means; means mounting said light source means to said mirror for emitting light in a direction to illuminate a subject in front of said mirror; and a polarized window in front of said light source means oreinted to polarize the light illuminating said subject in a second direction different from said first direction.
Claim 3
Dependent Claim
43 words
The structure of claim 1, in which said means mounting said light source means to said mirror includes means for changing the relative orientation of said window and surface whereby the angle between the first and second directions of polarization may be adjusted.
Claim 4
Dependent Claim
39 words
The structure of claim 2, in which said mirror is circular, said light source means being of annular configurations surrounding the periphery of said mirror, and said window being annular and lying substantially in the plane of said mirror.
Claim 5
Dependent Claim
43 words
The structure of claim 3, in which said light source means comprises the ends of a fiber optics array defining an annular configuration at the emitting ends of said fiber optics; and a light source at the other ends of said fiber optics.
Claim 6
Dependent Claim
46 words
The structure of claim 4, in which said means mounting said light source means to said mirror includes an elongated handle, a portion of said handle receiving said other ends of said fiber optics and housing said light source whereby a manually manipulable mirror structure results.
