3.2 THE TYPE 1531 STROBOTAC® ELECTRONIC STROBOSCOPE.<br />
3.2.1 GENERAL DESCRIPTION. The Type 1531 Strobotac electronic<br />
stroboscope (Figure 3-3) is a versatile, inexpensive, high-speed light<br />
source designed to fill a wide variety <strong>of</strong> both photographic and nonphotographic<br />
needs in science and industry. Its light weight and com<br />
pact design make it convenient to use, and its light output is suitable<br />
for taking many different types <strong>of</strong> photographs. (Refer to Section 4). A<br />
self-contained electronic oscillator enables the unit to operate indepen<br />
dently at flash rates from 110 to 25,000 flashes per minute. The flash<br />
rate is continuously adjustable throughout this range, and it can be ac<br />
curately set (±1%) by means <strong>of</strong> the large calibrated dial on the instru<br />
ment panel.<br />
The Strobotac is housed in a carrying case whose cover doubles<br />
as an adjustable stand (see Figure 3-3), and protects the instrument<br />
from damage while in transit. The unit can be easily carried to any<br />
location. Power requirements are flexible. Either 120- or 240-volt ac,<br />
50- to 60- or 400-cycle power is satisfactory; maximum input power is<br />
35 watts.<br />
