Photon Counter 1.5 GHz AmplifierInformationDetectors

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.  

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 four 1 GHz photon counting channels and one input trigger to start data collection
3.75" x 3.0"  double layer board for reliability and simplicity
3.3V @ 3.2 Ampere at maximum count rate of 4  Billion photons/second
PECL inputs (1.5 GHz amplifier-discriminator interface, next page) AC or DC coupled 50 ohm
     Photon input via Positive edge triggered  4 GHz flip flop accepting 125ps or wider pulses
     Trigger - Positive edge Positive Emitter Coupled Logic (PECL) or TTL
TTL outputs
      Triggered = 1 state, positive transition
      Four 8 bit byes of photon data
Interface - USB computer controlled acquisition for N triggers or continuous - lowest cost.
                DIO of 400 MEGABYTES/SECOND CONTINUOUS input to 64 Gigabytes of computer Ram
Software - IDL 3-D analysis software USB interface free
                 Upgradeable to full user control and custom user analysis programs
Note: One year warranty applies.

Interface  to various PMT's  including Hamamatsu 1 GHz Hybrid tubes is accomplished with the 1.5 GHz Variable Gain amplifier/discriminator on the next page which accepts positive or negative pulses.
