ABSTRACT:
An apparatus that reduces convergence and focus drift in imager prism assemblies includes at least one assembly having a first side and a second side. The first side communicates with a first isolator inner surface and a second side communicates with a second isolator inner surface. An outer surface of the first isolator communicates with a first member of a frame. An outer surface of the second isolator communicates with a top side of a damping member. A bottom side of the damping member communicates with a second member of the frame. There is at least one guide pin located through the first isolator and the first member.A first adhesive secures the first side to the first isolator inner surface and the first adhesive secures the second side to the second isolator inner surface. A second adhesive secures the first isolator outer surface to the first member and the second adhesive secures the second isolator outer surface with the top side. A third adhesive secures the bottom side to the second member and a bottom end of the first and second isolator communicates with a plate.
