Product Overview
Pacific Instruments 3150RF PMT Housing with Hamamatsu R666 Photomultiplier Tube - Used
This listing is for a Pacific Instruments 3150RF photomultiplier tube housing fitted with a Hamamatsu R666 detector module.
Pacific Instruments built housings that brought mechanical stability to low-light detection, while Hamamatsu PMTs became a benchmark in research labs worldwide. This pairing once served as a quiet backbone in experiments where a single photon could shape the outcome.
Product Condition
The housing appears in solid physical condition with an intact enclosure and clear rod mount. The Hamamatsu R666 tube remains installed. The assembly has not been electronically tested and is offered as-is.
Product Overview
PMTs are designed for sensitive photon detection in spectroscopy, nuclear instrumentation, and optical experiments. The Hamamatsu R666 is a head-on configuration tube with a uniform photocathode and multiple dynode stages for high gain and stable response. The Pacific Instruments 3150RF housing provides shielding, optical alignment, and a durable interface for integration into research setups. Together, they form a compact detection module suitable for laboratory instrumentation or experimental builds.

Frequently Asked Questions
Does the unit include the Hamamatsu R666 PMT?
Yes. The R666 PMT is installed within the 3150RF housing.
Has the PMT been tested?
No. The assembly has not been electronically tested and is offered as-is.
What differentiates the R666 model?
The R666 uses a head-on configuration with a round photocathode and multi-stage dynode chain for high gain and fast response in low-light applications.
What power does the PMT require?
The R666 typically operates with a regulated high voltage supply between approximately 500 and 1200 volts, depending on application and gain requirements.
Does the 3150RF housing provide RF shielding?
The housing is designed to support PMT operation with shielding and a controlled optical interface, helping minimize electrical noise in sensitive setups.
This assembly once lived in the world of precision optics, built when PMTs were the heartbeat of experimental detection. Now it’s ready to support the next project that needs a reliable path for faint photons to become usable signals.
