1. A five-degree-of-freedom ocular mounting assembly, comprising:

  • a rectangular-shaped ocular support assembly housing having a rigidly attached view angle hinge pin with opposing ends;

    a pair of ocular support arms slidably disposed within the assembly housing for supporting a pair of ocular devices rotatably attached to the ends of the ocular support arms, each ocular support arm having a slot with a set of serrated teeth, the teeth being substantially enclosed within the housing during operation;

    an interpupillary adjustment knob on the assembly housing having a set of serrated teeth which engage with the serrated teeth in the slots of the ocular support arms;

    an eyeglass mount having a protruding pad with parallel sides and a rigidly-attached flip-up hinge pin with opposing ends;

    a pair of clamp assembly members having slots that engage the flip-up hinge pin and the view-angle hinge pin, the assembly providing means for independent adjustment of each end of each pin;

    a height adjustment rail that engages with the pad on the eyeglass mount to allow the height of the ocular devices to be adjusted; and

    means to lock the pad into the channel at a desired height,wherein rotation of the interpupillary adjustment knob causes the ocular support arms to slide in and out of the assembly housing for adjustment of the interpupillary distance between the two ocular devices, the convergence angle and view direction of the two ocular devices being adjusted by rotating the ocular devices, the ocular support assembly about the view angle hinge pin and the ocular devices are flipped up out of the way by rotating the ocular support assembly and clamp assembly members about the flip-up hinge pin.
