Spark Product Innovation introduces the SPI-TCSPC-16 Time

Correlated Single Photon Counter. The SPI-TCSPC-16 is a scalable 16 channel, software configurable Time Interval

Analyser. The SPI-TCSPC-16 has 16 Independent input channels

synchronised by a single external clock or GPS signal. The SPI-TCSPC-16 is intended to be used in conjunction with the SPI-

TCSPC-SYNC module to enable up to eight SPI-TCSPC-16

modules to operate simultaneously, thus providing up to 128 input channels. The SPI-TCSPC-SYNC module also allows SPI-

TCSPC-16 modules to use a GPS derived time, allowing

experiments to be conducted across different geographical locations (in conjunction with the Ethernet data interface).

The SPI-TCSPC-16 utilises a software configurable TAC (Time to

Amplitude Converter) to allow experiments over a wide range of time intervals and repetition rates. The SPI-TCSPC-16 has a time

bin resolution of range of 1to 4ps depending the TAC ramp-rate

selection. The SPI-TCSPC-16 is housed in an ultra compact, rugged, six

sided aluminium EMI enclosure. The compact design permits

direct mounting (either horizontally or vertically) onto a standard optical test bench to help minimise sensor cable lengths and

reduce overall bench space requirements.

Spark Product Innovation can also offer customised timing & synchronising hardware as well as histogrammer & correlator

software tailored to suit the requirements of your experiment.

systems in different physical locations. Tags are stored in FIFO memory ready to be delivered across hardware interfaces allowing for high speed burst collection of tags on multiple channels. FIFO depth 65536 Tags.

GUI & Software Modular Software approach: Modular software system. Modules for histogram generation, coincidence counting,

and bespoke modules available for specific customer applications Flexibility Python & Labview interface provided for customers own interfacing. Network capable With Ethernet option, instrument can be setup as a multicast server, allowing

multiple software connections to a single instrument by subscribing to the multicast group. Good for larger labs where many clients need access to tag information from group detector sources.

Simple instrument interface: Instrument management interface, for choosing Sync source, setting TAC mode and setting up tag delivery process.
