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 Specifications: 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.
