Extended-duration stroboscopic flash The ESD-VF2M-U2 stroboscope employs a unique lighting system
to enable ultrahigh-speed time-elapsed video recording by providing flash for a
relatively long duration (50 ¥ìsec to 2 msec), instead of flashing for each
frame. The lighting system consists of the ESD-VF2M-U2 Strobe Driver and the
SLA-153-U1 Lamphouse. For video recording of a recurring phenomenon, the FG-310
pulse generator can be added so that the record timing can be set easily while
observing the phenomenon directly with the eye.
Suitable for ultrahigh-speed video cameras capable of shooting 50,000 frames
to 1,000,000 frames per second.
For an increased illumination effect, either one-lamp flash (13.2-W input)
or four-lamp flash (2.2 W each) can be selected.
The flash time can be varied within a range of 50 ¥ìsec to 2 msec so that
unnecessary illumination can be reduced.
For video recording of a high-speed recurring phenomenon, the product can
also be used as a stroboscope by dividing the synchronizing signal (FG-310 pulse
generator required).
Since the product is a strobe flash, it is capable of providing high
momentary light intensity. It is also compact and easy to use. The unit
generates minimal heat, allowing for safe use. (As the product generates high
voltage, do not touch the inside of the unit. Internal high voltage can cause
serious accidents and injuries.)
Voltage signal or current loop can be used as a flash starting signal.

Multi Flash Stroboscope ESD-MF20 is a light source for high-speed video cameras providing
flashes (up to 20 flashes at a time) for a relatively short duration (10 to 100
msec) in very short cycle time of 50 msec in synchronization with each video
frame.
