Photon Counting PMT Detection System
-
For spectroscopy and microscopy experiments in the UV/Vis/NIR region of the spectrum, a photomultiplier tube (PMT) is the ideal detector for quantitative low light level measurements. A PMT is extremely sensitive, with very wide dynamic range so it can also measure high levels of light. PMT’s are also very fast so rapid changes in optical signals can be reliably monitored. As a practical matter, PMTs are durable, long-lived, and economical.HORIBA provides a simple, self contained PMT housing that operates in either analog or photon counting modes with the flick of a switch. This ambient PMT housing is ideal for standard side-on PMTs that are used from 185 to 900 nanometers. It has a very low dark count for a non-cooled PMT housing providing a dark count of only ~ 50 to 500 counts per second (cps) depending on the PMT selected.

Delays And Gates
-
Delays, Gate and Delay Generators, Logic Modules, and Linear Gates are used in many research or teaching experiments and in non-research applications such as actively shielded spectroscopy systems. Delay modules allow the alignment in time of signals from different paths, so that a logical decision can be made within a logic module which will often result in an electronic go/no-go decision as to whether a particular detector analog output will be processed within an associated multichannel analyzer.

Amplifiers
-
Amplifiers are used to amplify the energy output of photodetectors as well as convert their electrical signal for a number of illumination measurement or spectroscopy applications. Amplifiers are digital systems that amplify the low electrical current transmitted by photodetectors to easily detectable levels. Amplifiers also convert photodetectors' electrical current into voltage so that their signal may be read by other digital devices. Amplifiers are indispensable for nearly any light measurement applications by greatly increasing the usability of a detector system.
