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.
