This 10mm focal length lens, manufactured by J.A. Maurer, Inc., was used on the data acquisition camera (DAC) placed in the Apollo 11 Command Module during its July 1969 mission. To document different technical procedures during the mission, such as docking and undocking with the lunar module, different lenses were available to the astronauts in order to capture these mission elements. A lens of this type would offer a fairly standard viewing angle of the subject.
