GenRad LogoGenRad / General Radio 1531-AB, 1538-A Stroboscopes

GenRad 1531-AB & GenRad 1538-A Stroboscopes

These stroboscopes are small portable flashing-light sources used to measure the speed of fast-moving devices or to produce the optical effort of stopping or slowing high-speed motion for observation.

Many U.S. government military and regulatory agencies specifically call out and/or reference these strobes. These products continue to be built and serviced in the Genrad tradition....

Genrad 1531 and 1538 Strobotac Photo

The 1531 is more economical to buy. On the other hand, the 1538 gives you six times the maximum flash rate of the former, and portable operation is possible with a rechargeable battery. The 1538-A can also supports an optional extension lamp.

The 1531-P2 Flash Delay is a valueable asset to any stroboscopic or high-speed photographic application. The 1531-P2 flash delay synchronizes the strobe with rapidly moving objects and controls the flash, relative to the position of the object, by introducing a variable time delay in the electrical path between the trigger source and the strobe.

Model Flashes Per Minute Flash Duration (approx.)
1531 690 to 25,000 3 to 0.8 µs
1538 690 to 150,000 3 to 0.5 µs
