SC-51 System System with large photocathode A large photocathode of up to 35 mm is available with streak camera systems using the SC-51 main unit. This allows simultaneous analyses of multiple optical phenomena typically required for high-dynamic laser doppler interferometry applications. A set of fixed width slits is proposed to be directly coupled to the fiber optic input window without additional optical elements. Input optics can be completed with an elecro-mechanical shutter and fiber optic marker inputs as well as F-mount adapter for lens mounting. For single photon detection sensitivity, a large format image intensifier unit is available. SC-51 systems can be considered to replace older Thomson streak cameras TSN. - Large Photocathode 35 mm - High spatial resolution - Photocathode gating - Detonics research
