A new light source improves the accuracy and sensitivity of high-speed video, ultra high-speed framing camera, Schleiren imaging and Shadowgraph systems. The SI LUX640 laser illumination system, made by Specialised Imaging in conjunction with Cavitar, is based on proprietary pulsed high-power diode laser illumination technology, which can illuminate an object up to a million times a second. The pulsed light power is typically several hundreds of watts, and the brightness is far greater than with LED light sources. The light pulses produced are so powerful and short that they can provide precise frozen images of transient events of just 100s of nanoseconds duration. Specialised Imaging
