A woman examining prisms with a loupe, 1937
At a bench beside other women, a worker in a light blouse lifts a small triangular block of glass from rows of identical pieces and holds it close to the loupe in her eye; in close view her fingers turn the prism so that its faces catch the light. Prisms of this kind folded the light path in binoculars and rangefinders, instruments for which the army and navy were placing ever larger orders.
