Marina Photonics is dedicated to Gigahertz affordable Time-Correlated photon counting systems and has been supplying high speed photon counters since 1987. Affordable means less than $5000 for most complete systems. (Excluding detectors) Affordable Continuous Streaming Time-Correlated Single Photon Counters are all Gated and USB3 output Channel 1 - 1.6GHz maximum sustained count rate Channels 2,3 - 800 MHz simultaneous count rates
Three or four channels of photon counting are available with sustained correlated count rates and no dead time or lost counts or FIFO limit. There is no start-stop reset time limiting sustained count rates. Once photon counting is triggered, the counter places photon counts in 1.25ns or 625 picosecond bins onto the computer disk through USB 3 until the process is finished or temporarily stopped by gating the counting. The number of counts to be collected is chosen by software. The photon counter board has a manual or an external input trigger to precisely start data collection and gating to collect only relevant data..
Specifications:6.25"w x 4.25"h x 7"d including switches and connectors Internal 100-240 VAC 50/60 Hz 10W Photon and gate and trigger inputs may be any level up to 3.2V, LVTTL GHz logic or PECL for better timing with positive edge.
Trigger Start - GHz LVTTL (or any preset positive level greater than 0.05V adjustable)
GHz LVTTL adjustable threshold edge Gating to select count windows for bursts of photons as short as 1.25 ns
Interface - USB 3 computer controlled acquisition at 400 Megabytes/second Unlimited continuous streaming throughput. Please see the second tab above for a picture of the New USB 3 version (coming soon)
Software - Data is stored on computer disk by a call to a command line program IDL 3-D analysis software interface is available that can be upgraded for custom applications. Any user software that can read binary files from disk may be used. Note: One year warranty applies to hardware and software updates.
