012-02119C Stroboscope
The PASCO Model SF-9211 Stroboscope provides
sufficient white light for strobe photography and for
"stopping the motion" during laboratory experiments. The
light is produced with a Xenon flash tube in a 14cm
diameter polished reflector. Flash rate is adjustable from
1-300 flashes per second and a digital display reads the
flash rate in either flashes per second or in RPM. For
added convenience, a threaded hole (1/4-20 UNC-2B) is
provided in the bottom of the unit for mounting the
stroboscope onto a tripod.
A variety of special features enhance the utility of this
stroboscope. For situations requiring synchronized flashes
to large or isolated areas (e.g. separate rooms), it is
possible to synchronize the strobe flashes of a number of
Model SF-9211 Stroboscopes. Each stroboscope
produces a 5 volt output pulse with every flash. This
output may be used as an external trigger that will cause a
simultaneous flash in a second stroboscope. By using the
output signal from each stroboscope to trigger the strobe
flashes of another unit, any number of stroboscopes may
be synchronized.
The ability of the stroboscope to respond to an external
trigger also allows strobe flashes to be synchronized with
some external event. This feature can be used to provide
automatic adjustment of the flash rate in response to rate
changes in the event being observed. It can also insure a
photograph is taken at a critical instant when performing
strobe photography.
To trigger the stroboscope from an external event, a 3-50
volt pulsed signal will trigger the stroboscope.
