A kinematic alignment structure is provided for use as an attachment to a lens barrel. This kinematic alignment structure is well suited for controlling perpendicular orientation of a pair of mirrors carried in a lens barrel that is transversely connecting two parallel lens barrels. The transverse lens barrel carries the mirrors on each end of the transverse lens barrel. The mirrors have a substantially perpendicular orientation from each other. The alignment structure microscopically adjusts the perpendicular alignment of the couple of mirrors. The alignment structure comprises a set of three positioning knobs distributed on each end face of the lens barrel. The mirrors are positioned in direct contact with the lens barrel via the set of three positioning knobs. The positioning knobs comprise a platform, and have raised tubular bodies and spherical top surfaces. The spherical top surfaces may be polished to microscopically adjust the perpendicular orientation between the two mirrors.
