Multiple framing camera works at high speeds
A multiple framing camera represents a novel instrumental approach that overcomes the traditional problems associated with simultaneous high-speed image capture.
Multi channel framing camera
The new SIM Multi-Channel Framing Camera from Specialised Imaging takes the capture of images for accurate, high-speed spatial analysis of transient events to a new level.
Normally, the overall time window for which the image capture occurs will be a few hundred microseconds so short duration high-intensity illumination sources are required for this type of recording.
The new SIL 500 Joule flash lamps generate extremely high intensity illumination for short time periods (2 mSec) that can be easily controlled and precisely synchronised to match the time frame of an event being recorded by a ultra high speed camera.
The new generation flash lamps are the result of considerable input from people who use high speed imaging for analysis of fast phenomena.

Cameras, accessories, spares and training
Specialised Imaging, a manufacturer of leading-edge performance ultra-high speed imaging systems, has been awarded a contract from QinetiQ to supply six of its innovative SIR2 cameras.
The small size of the source, the high intensity light output and the rugged packaging are the result of direct consultation and cooperation.
SIL 500 Joule flash lamps operate on the principle that electrical energy is stored in large capacitors and then released on command into a specially designed flash tube and in doing so creates a high energy luminous discharge.
Xenon, which is used in the flash tubes, unlike other some gases, produces a spectral output which has energies at virtually all the wavelengths of the visible spectrum making it suitable for both film and solid state sensors.
The life of the flash tube is rated in thousands of hours so rarely requires replacing.
Another advantage of the new flash lamps is the small power source required to produce the necessary levels of illumination.
Conventional tungsten filament lighting that could provide similar output characteristics to the new flash lamps would require many tens of kilo watts of energy as much of that energy is expended as heat.
The SIL 500 Joule flash lamps are cheap to run as they use very little energy.
The SIL flash lamps also produce negligible amounts of heat because the illumination results from the excitation of gas molecules.
As the luminous intensity is much higher than conventional tungsten lighting the illumination from the SIL 500 Joule flash lamps can be concentrated onto much smaller areas of interest.
