A polished lens block, close view, 1937

Close in: a block studded with gleaming lenses lies in the foreground, each disc reflecting the window light, while behind it a worker's hand guides a polishing tool over a second block turning on its spindle, easing it on and off. The finished surfaces had to be accurate to a fraction of the wavelength of light.

Period: c. June 26, 1937–October 8, 1937
