High-Repetition Rate Stroboscopic Light Source

The open time of a Fastax rotating-prism shutter is 40 μsec at 5000 frames/sec. Better action-stopping is achieved with a 1-μsec stroboscopic light. A 5C22 triggered by Fastax sprocket teeth discharges a 12-kv pulse-forming network into an Edgerton lamp 5000 times/sec. An area 3 × 3 ft is adequately illuminated for reflection photography with ASA 100 film at f/2.7.
