The single or multiple spark gap COMBI SPARK serves for photographic recording of rapid events by means of either a single flash or of several time controlled spark gaps. When using a large size plate camera and superposition spacial separation of the object phases is effected by object movement. The instrument consists of spark head(s) and control unit. Firing of the flashes is effected over a retarder which can be steplessly adjusted over five decades. In case of multi spark gaps, the firing intervals between individual flashes can be adjusted independently from each other. The spark head contains triggerable spark gaps in coaxial design which are mounted in a pressure housing. Fillings with different gas mixtures can vary flash duration and light output. The COMBI SPARK can be employed both as front light or back light in motion analysis experiments in a wide variety of research fields, e. g. dynamic material stress, ballistics as well as shock wave investigations.
