PMTsFor spectroscopy experiments in the ultraviolet-visible–near infrared region of the spectrum, a Photomultiplier tube (PMT) is perfect for the detection of light. Standard PMTs can be used from 185 to 900 nanometers; special PMTs can expend this wavelength range.

A PMT is extremely sensitive, allowing the measurement of very low levels of light. It has a wide dynamic range, so it can also measure high levels of light. It is very fast; so rapid spectral events can be reliably monitored. As a practical matter, PMTs are durable, long-lived, and economical. And with OBB’s Photomultiplier Detection System, it is very convenient and easy to use.

The Photomultiplier Detection System 3000 from OBB Corp is built as complete system using modern design techniques and components. You won’t find anything like them elsewhere. Everything needed to measure the intensity of the light is packaged in a compact, attractive housing that attaches conveniently to your experiment. There are no unsightly boxes for power supplies or a multitude of cables tangled on your bench-top.

The system incorporates a high voltage supply, detector electronics, and the controls in a compact, attractive housing that also contains the PMT. You have a choice of standard PMTs to choose from, the reason why they are not included with your system. The PMT high voltage is shown on a digital display on the housing or you can select to show the actual analog signal from the PMT with just a flip of a switch. The high voltage can be adjusting manually or controlled externally with a signal at the “External Voltage Control” BNC. Power is delivered from an external supply that is included. Computer interface and Microsoft compatible software complete the package.
