Streak Camera C2830
Streak cameras high-speed light detectors which enable direct measurement light phenomena with unsurpassed temporal resolution. They simultaneously measure time, position wavelength) light intensity, process data real-time using dedicated read-out system. Streak Camera C2830 equipped with either plug-ins: fast-speed (for better than resolution) slow-speed (for better than resolution) sweep unit. addition, C2830 high-speed electronic shutter which eliminates unnecessary incident light during nonsweep period makes possible sampling measurements continuous phenomena.
FEATURES Designed single sweep operations Covers wide time range from (using both fast slow sweep plug-in units) Temporal resolution Fast sweep unit: Better than Slow sweep unit: Better than Simultaneous measuring time, position wavelength) light intensity High sensitivity (single photoelectron detectability) High-speed gate function
Plug-in Sweep Units Available: Fast Sweep Unit Slow Sweep Unit

OPERATING PRINCIPLE
streak camera converts incident light into electrons performs high-speed sweep (deflecting electrons from bottom), enabling detection time variation incident light intensity converting these into different positions screen. figure below shows operating principle streak tube, which forms heart streak camera. light pulse measured focused onto photocathode streak tube through slit, where photons converted into number electrons proportional intensity incident light. These electrons accelerated conducted towards phosphor screen, high-speed voltage which synchronized incident light applied. electrons swept high speed from bottom then multipled (micro-channel plate), after which they bombarded against phosphor screen streak tube converted optical image. optical image which appears phosphor screen called streak image, shows intensity distribution incident light, which positions electrons determined perpendicular direction over passage time. Using this method, temporal intensity distribution light being measured displayed spatial intensity distribution phosphor screen.
