  • MCPC618 Photon Counting System
Aug 2010
Vertilon Corp.Request Info
WESTFORD, Mass., Aug. 16, 2010 — Vertilon Corp. has launched the PhotoniQ MCPC618 eight-channel high-speed photon counting system for photomultiplier tubes and silicon photomultipliers.

The data acquisition system uses photon counting as the primary signal measurement technique. The company said that it developed the system to meet the needs of customers requiring precision ultralow-light level sensing at speeds of up to two billion photon counts per second.

The instrument is designed to directly interface to high-gain optical devices without the need for external preamplifiers or other electronics. Each independent channel can resolve photon occurrences at an event pair resolution of <4 ns at sustained counting rates exceeding 250 MHz per channel. When triggered, signal count data is simultaneously acquired across all channels and transferred to a PC through a high-speed USB connection.

Data can be displayed on the PC using an included graphical user interface or streamed to the user’s real-time custom software application. The microGate feature, when synchronized to a user-supplied timing signal, allows the counting process to be selectively enabled or disabled with subnanosecond resolution. This feature is useful in applications where counting must be inhibited while an excitation source such as a laser is active.
