During the Apollo 11 luanr mission of July 1969, astronauts Neil Armstrong and Buzz Aldrin carried this specially designed Minolta light meter on the lunar surface in order to acquire accurate exposure information quickly and easily. The silver metal casing reflected some of the harmful solar rays that could have overheated this sensitive equipment.
NASA transferred this spotmeter to the Museum in 1970.
