Abstract
Abstract A casing structure supports a circular mirror having a flat polarized surface and an annular window surrounding the circular mirror. A single light source in the casing has its light directed to an annular reflector for passing light out through the annular window to illuminate a subject looking into the circular mirror. The annular window is polarized in a direction different from the polarization of the mirror and may be rotated relative to the circular mirror to change the angle of the respective polarization.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
256 words
A cosmetic mirror including, in combination: a. a casing structure; b. a circular mirror supported by said casing structure and having a flat mirror on its front surface polarized in a first direction and a concave mirror on its rear surface polarized in said same first direction, said casing structure supporting said circular mirror in a manner for rotation about a diameter corresponding to said first direction of polarization whereby said circular mirror may be rotated about said diameter 180° so that said concave mirror surface faces forwardly and provides a magnifying mirror; c. an annular window coaxially surrounding the circular periphery of said mirror and supported by said casing structure for rotation in its own plane about its axis, said annular window having a surface polarized in a second direction different from said first direction; d. a single light source supported in said casing structure behind said circular mirror on the axis of said circular mirror; e. a primary mirror on the axis of said circular mirror between said circular mirror and light source for directing light rearwardly and upwardly; and f. a secondary mirror of annular configuration positioned to intercept said rearwardly and upwardly directed light from said primary mirror and pass it through said annular window to illuminate a subject in front of said flat mirror surface whereby the light falling on said subject is polarized in said second direction and whereby changing the rotative position of said annular window will vary the difference angle between said first and second directions of polarization.
Claim 2
Dependent Claim

A cosmetic mirror including, in combination: a. a casing structure; b. a circular mirror supported by said casing structure and having a flat mirror on its front surface polarized in a first direction and a concave mirror on its rear surface polarized in said same first direction, said casing structure supporting said circular mirror in a manner for rotation about a diameter corresponding to said first direction of polarization whereby said circular mirror may be rotated about said diameter 180° so that said concave mirror surface faces forwardly and provides a magnifying mirror; c. an annular window coaxially surrounding the circular periphery of said mirror and supported by said casing structure for rotation in its own plane about its axis, said annular window having a surface polarized in a second direction different from said first direction; d. a single light source supported in said casing structure behind said circular mirror on the axis of said circular mirror; e. a primary mirror on the axis of said circular mirror between said circular mirror and light source for directing light rearwardly and upwardly; and f. a secondary mirror of annular configuration positioned to intercept said rearwardly and upwardly directed light from said primary mirror and pass it through said annular window to illuminate a subject in front of said flat mirror surface whereby the light falling on said subject is polarized in said second direction and whereby changing the rotative position of said annular window will vary the difference angle between said first and second directions of polarization.
Claim 3
Dependent Claim
28 words
A cosmetic mirror according to claim 1, including rheostat means carried on said casing and connected to said light source for varying the intensity of said light source.
