Abstract
A high accuracy periscope assembly is provided. The high accuracy periscope assembly of the invention is comprised of a hollow tubular member and two mirror panels. The tubular member has slanting surfaces at ends thereof and openings to allow light beams to enter, pass through and exit the tubular member. The mirror panels have reflective surfaces for reflecting the light beams and mounting pads for adhering the mirror panels to the tubular member. Alignment pads are also provided which have contact pads and a reinforcement member. The reflective surfaces of the mirror panels are aligned and then the alignment pads secure the mirror panels in their aligned positions without disrupting the kinematic mounting of the structure.
