Photomultiplier tubes, often known as photomultipliers or PMTs for short, are incredibly sensitive light detectors that can detect light in the ultraviolet, visible, and near-infrared spectrums. They belong to the category of vacuum tubes, more especially the category of vacuum phototubes.
In numerous dynode stages, these detectors may amplify the current created by incident light by up to 100 million times or 108 that is , 160 dB, allowing for example the detection of individual photons when the incident flux of light is minimal.
Photomultipliers continue to play a crucial role in nuclear and particle physics, astronomy, confocal microscopy, Raman spectroscopy, fluorescence spectroscopy, medical diagnostics, including blood tests, medical imaging, motion picture film scanning (telecine), radar jamming, and high-end image scanners.
These applications include low light level spectroscopy, blood tests, medical imaging, motion picture film scanning (telecine), radar jamming, and high-end image scanner Night vision equipment is built on components of photomultiplier technology that have been differentially incorporated.
A laser and a PMT are frequently used in studies that evaluate light scattering, such as the research of polymers in solution, to gather the scattered light data.
However, photomultipliers are particularly well-suited for applications requiring low-noise, high-sensitivity detection of light that is imperfectly collimated. Alternatives to conventional photomultipliers include silicon photomultipliers and avalanche photodiodes.
The Global microscope photomultiplier photometer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Any lab wishing to quantify the amount of light coming from a sample on a microscope stage will find HORIBA’s microscope photomultiplier photometers to be the perfect solution.
These photometers were originally developed for the most difficult low light level fluorescence kinetics of tagged mammalian cells, but they are also excellent for mineral analysis or transmission research.
Pairs to any microscope C-mount and has the features of being compact, user-friendly, and relatively economical. Analog or photon-counting detector with BNC signal output to any A/D interface A variable target aperture, single, double, or triple detector channels.
