This lens and attache mirror were used with the 16mm Data Acquisition Camera (DAC) manufactured by J. A. Maurer Company for the Apollo program. DACs were used in both the command and lunar modules during the program, and this lens was tested on the first circumlunar mission (Apollo 8) and again on the first test of the lunar module (Apollo 9). The right angle of the lens/mirror attachment was tested for difficult angled photographs from the command module windows. The command module version camera, lacking a window mount found in the lunar module versions, was used to gather information during technical procedures such as undocking and redocking the lunar module (only for Apollo 9).
This camera was transferred to the Museum from NASA in 1977.
