Abstract
The present invention is a device for adjusting the magnification of a flexible mirror and a method of making the same. The device includes a flexible mirror having a reflective surface and a rear surface surrounded by a periphery. The device also includes a housing having a retainer member for retaining the mirror and a base member supported on the housing. The base member has an aperture therethrough and includes a plurality of angled guide members located about the periphery of the aperture. A retention member, which is connected to the rear surface of the mirror, includes a protrusion which is received in an aperture of an adjustment member and permits the adjustment member to rotate freely about the retention member. The adjustment member also includes a plurality of retainer members which are inserted into the aperture of the base member and engage the angled surfaces of the guide members. The adjustment member may be rotated in a first direction to displace the retainer members along the angled surfaces to cause the generally flat mirror to assume a concave shape and in a second direction to flatten the mirror.
