Line scan tube designed for application on the Lunar Orbiter, measuring 19? x 9? x 9.5?, marked on the side: "Line Scan Tube: Unit No. 12, Pt. No. V1212-1000, Ser. No. 013A, Spec. No. 1225-118, Date Mfd. 3|4|66, Contr. No. NAS1-3800, P.O. No. N649500-9572, Mfd. by CBS Labs for Eastman Kodak Co." In very good to fine condition.

The line scan tube was part of the Lunar Orbiter's photographic readout system: after the film was developed onboard the spacecraft, the line scan tube shot a thin beam of light across its surface. Behind the film, a photo-multiplier tube sensed the variations in the beam of light caused by the film's density. The resulting output was then amplified and transmitted to ground receiving stations on Earth via the Orbiter's communications subsystem, where the data was reconstituted into photographic imagery.
