PMT



		PMT Housings General Information For spectroscopy experiments in the ultraviolet-visible-near infrared region of the spectrum, a photomultiplier tube (PMT) is perfect for the detection of light. PMTs can be used from 180 to 1200 nanometers. 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.


		PTI's 800-Series Photomultiplier Detectors include everything needed to measure the intensity of light in a compact, attractive package that attaches conveniently to your instrument.


		The Model 810 is a photon-counting detector with high-voltage power supply, digital HV display and discriminator all built-in. The Model 814 Analog/Digital PMT Detector allows you to choose between analog and photon-counting detection. In analog mode, you don't even need any external data gathering, displaying or recording equipment--the analog signal is displayed directly on the unit's built-in LCD meter. Other unique features of the 800 Series includes the ability to measure the signal directly from the PMT anode.


		The new Model 820 interfaces with a cooled PMT housing, eliminating the need for bulky external power supplies and signal processing electronics. The signal from an 800-Series PMT Detector can be processed in a variety of ways. Depending on your application, you can use a digital multimeter, a recorder, or a computer. PTI's new SID-101 monochromator controller accepts the output from any 800-Series housing and sends it to the com port of any PC.
