An interesting Space Shuttle/Mir optical rangefinder assembly, measuring 23 x 4.5 x 2.5, marked on the side, "Rendezvous Rangefinder Assy, SED33103319-301, S/N 1005." The assembly features a long gray tube with an optical port at one end, connected to a box with dual optical ports. The unit also has a smooth-rotating dial with a distance measurement scale at one end. Typical blue Velcro swatches are affixed to the assembly. In fine condition. Accompanied by a fitted storage bag. While obviously developed for application on the Space Shuttle, there is no evidence that this technology was used on orbit; laser range finders, which would be more precise than their optical counterparts, were the primary aid for crew queuing of distance during rendezvous operations between American Space Shuttles and the Russian space station Mir. The optical rangefinder may have been developed as a backup in situations where the laser rangefinder was unable to lock on targets that weren't reflective enough.
