ALV-6010 / 160, Ultra-Fast External Correlator (EPP Communication) | ||||||||||||
For all such applications, requiring ultra-fast sampling times below 10 ns. The ALV-6010 Correlator Series can either be used in the ALV-5000/EPP compatibility mode (125 ns STC SINGLE MODE, 250 ns DUAL MODE), or at 5 ns (6.25 ns) initial STC, whenever the fast sampling times are required. In contrast to the ALV-5000/EPP compatibility mode, the FAST MODE always is a cross correlation mode - at such fast sampling times, the use of auto correlation would turn out to be absolutely useless anyway - even very good single photon detectors can not be used below 100 ns sampling / lag time without imposing strong distortions (afterpulsing and dead times) to the resulting correlation function. Using cross or “pseudo cross” correlation totally overcomes this problem (see as well the SINGLE PHOTON DETECTION section of this homepage). | ||||||||||||
Application
Important Note ! For best performance in FAST MODE, the ALV-6010/160 should be used with specially optimized single photon detectors, such as the ALV-SO/SIPD-II or the ALV-DUAL High Q.E. APD !
