The Pulse Photonics high intensity variable duration light unit.

When recording high-speed phenomena using microsecond exposure times it is essential that adequate light is available to ensure that well exposed images are captured. Tungsten based light sources produce more heat than usable illumination consequently many kilowatts of lighting are required, which is often difficult to concentrate onto a small area of interest. The most practical alternative is the short duration Xenon flash source that can generate high intensity illumination for a few tens of milliseconds. This type of light source can be readily controlled to coincide with the area of interest and the recording window of the high-speed camera and produces little or no unwanted heat. By the careful selection of lenses or fibre optic light guides intense illumination can be directed to confined areas which would be impossible to illuminate by other means.
