             Affordable Continuous 4 Gigaphotons/second

Marina Photonics is dedicated to high speed affordable Time-Correlated photon counting systems and has been supplying high speed photon counters since 1987.  
                        2 Channels  - Two Gigaphotons/second  - $2,000

                         Time-Correlated Single Photon Counting

Two to four channels of photon counting are available with 1 GHz per channel sustained count rates with no dead time or lost counts.  There is no start-stop reset time.  Once photon counting is triggered, it continues to place photons in one nanosecond bins until the entire process is stopped by a reset. The photon counter board contains up to four 1 GHz photon counting channels and one input trigger to start data collection.  Start can also be manually or software initiated
