Stroboscope for high-speed vision
applications
The BVS-II Wotan stroboscope is specially designed for high-speed industrial vision applications where short duration, high intensity light pulses are necessary to 'freeze' the motion.
New from Polytec, the BVS-II Wotan stroboscope is specially designed for high-speed industrial vision applications where short duration, high intensity light pulses are necessary to 'freeze' the motion The high intensity light pulses not only minimize image smearing by decreasing the exposure time but also reduce ambient light problems by dominating the illumination intensity

20,000 3D profiles per second possible
Sick IVP has released a new series of the Ranger vision camera's capable of acquiring 20,000 3D profiles per second.
A convenient fibre optic system allows the user to choose from many different accessories to improve the illumination pattern The key component of the strobe unit is an ultra-stable short-pulse xenon flash lamp.
The xenon flash system is an excellent stabilized pulsed light source for industrial illumination tasks.
Rapid image sequences can be handled by pulse repetition frequencies up to 200 Hz.
Exposure control and colour balance are simplified by low pulse-to-pulse intensity fluctuations and a colour temperature of 5000 K.
The fibre-optic system is an extremely versatile solution for industrial illumination.
It allows the light source to be removed from hazardous or dangerous environments while guiding the light to the exact location where it is needed.
The system begins with an ellipsoidal reflector to focus the xenon light output into the fibre-optic.
Due to the large fibre acceptance diameter at the strobe flange, many fibre bundles may be adapted.
The system ends with a variety of standard fibre-optic heads (goosenecks, ring lights, light lines, backlights etc) that provide appropriate solutions for many different illumination tasks.
200 Hz pulse repetition frequency (maximum) Maximum pulse energy: 2.16 J @ 20 Hz Fast strobe pulse (<6 µs) 5000 K colour temperature Keypad or remote (RS-232) strobe setup; external inputs for trigger and intensity control Universal power supply voltage (85 VAC - 265 VAC ) Burst Mode for multi-pulse function 3 ms adjustable delay between trigger and pulse (maximum) Very small pulse-to-pulse intensity fluctuation (< 2.5%) 9-device "strobe-network" possible.
