Abstract: A mounting assembly for securing a holster to a user that permits a holstered weapon to be rotated from a normal, dominant-hand accessible position to a reversed position more easily accessible to a non-dominant hand. The assembly includes a first portion that is securable to a user and a second portion hingedly connected to the first portion in a manner allowing rotation about a generally upstanding axis. The second portion is rotatable between a normal position which enables the user to draw the weapon using a dominant hand and a reversed position in which the holster is rotated to enable the user to conveniently draw the weapon using an off-hand. The assembly includes provisions to restrain the second portion in one or more predetermined orientations, biasing mechanisms to rotate the second portion when released, and latching mechanism to prevent inadvertent or unintended rotation of a holstered weapon.

Abstract: A reflective thin film polarization retardation device which is adapted for use in active mirror laser apparatus is described. The device permits obtaining phase retardation of light, different amounts of which may be readily obtained. Retardation results from interference effects within thin film arrays within the device. A polarization rotator utilizing the invention is made up of a thin film reflective transmissive polarizer, a thin film reflector and a phase adjusting layer, which may be one or more thin film layers. The phase adjusting layer is sandwiched between the thin film polarizer and the thin film reflector. The thin films constituting the polarizer, phase adjusting layer and reflector may be successively deposited on one of the planar faces of a body of laser glass, with the films constituting the polarizer being deposited first.
