A totally new approach has been taken to develop an image intensifier for use in front of high speed rotating prism and image converter cameras at framing rates up to 1 million pictures per second. Cinemax II is a high brilliance image intensifier which can also record UV radiation down to 180 nm, increasing the scope of the automotive engineer investigating the combustion process. Cinemax II is gated on at a frequency of 100 Hz to facilitate setting up and wide aperture critical focussing. Variable gain allows the image brightness to be adjusted to satisfy different subject lightning conditions. In operate mode the gate on period can be readily synchronized to the event and camera to ensure optimum results are achieved and safety thresholds are not exceeded. Cinemax II has successfully been used with the Imacon 792, Photec, and Hyspeed cine cameras for combustion and plasma research.
