Stroboscope enables dynamic activities to be easily visualised without motion blur
Germany's Polytec GmbH says that its stroboscope BVS-II Wotan is an ideal illuminating system for applications that required extremely short and high-intensity light pulses.
This allows dynamic activities to be visualised without any motion blur. The stroboscope is able to freeze movements to create sharp pictures with a high degree of contrast in changing, ambient light conditions. At the heart of the system is an ultra-stable, pulsed xenon flash-lamp. The light produced by this lamp is focused by an elliptical reflector into fibre optics.
The BVS-II Wotan has a maximum pulse frequency of 200 Hz. An integrated microprocessor achieves an excellent pulse-to-pulse stability of typically 2.5 %, says the firm. The desired intensity can be defined by an analogue signal, by a computer's interface RS232 or by setting the default value from the control panel.
The colour temperature is about 5000 K. Triggering is achieved via a TTL signal (5 V), SPS (24 V) or PAL/CCIR-video signal. In the burst mode, one trigger signal can deliver several pulses. In addition, it is also possible to synchronise several stroboscopes.
Polytec is also distributing an LED lighting system developed by Swedish company LAT Elektronik AB. The 300-mm dome light has an integrated ring light on top of the unit and three circles of 'satellite' LEDs. All LED groups are controlled individually. The dome creates diffuse light, while the ring generates incident light and the satellite LEDs illuminate certain areas of the object.
