Here we see the diamond wire saw cutting
(actually dicing) an anti-reflection coated bar into a series of
microprisms. The glass is mounted on a three axis
goniometer (under plastic wrapping). The wire saw blade is
diamond coated, produces an 0.008" kerf and is coated with
50 micron diamond powder. It produces a fine ground finish
free from chipping and scratches. It is slow but it saves
downstream processing steps.
