- synchronizes and times flash
- sdjustable time delay from 0.1 ms to 800 ms for stopping motion at any point in cycle
- is easily synchronized with camera for single-flash operation for brightest possible flash
- easily attached to 1531-AB, 1538-A, 1539-A and 1546 stroboscopes
The 1531-P2 is a valuable asset to any stroboscopic or high-speed photographic application. The 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 (transducer, contact, photocell, etc) and the strobe. In stroboscopic applications this delay allows you to position the stopped motion to any point of interest in the action. By the simple turn of a knob, you can reposition the image to illustrate a dozen, or even a hundred, points in order to analyze completely all aspects of the motion.
For photographic records, a single-flash mode is provided. Once the delay has been set so the image is posi-tinned properly, the mode is set to Single Flash and the flash will then occur only when the camera shutter is released and the action is in the proper position. This mode allows the brightest possible flash and eliminates blur.
