| After collection of the emitted photons on a photomultiplier, the signal is digitized with a numerical oscilloscope. |
|
| Samples were also simultaneously imaged using the secondary electrons that were detected by a photomultiplier. |
|
| The light scattered by a particle passing through these beams is collected and focused on a photomultiplier tube. |
|
| Spectra were also corrected for the wavelength-dependent efficiencies of the photomultiplier tube detector and monochromators. |
|
| Detection was achieved using a monochromator coupled to a photomultiplier tube. |
|
| This latent image is then read out with a photomultiplier that detects the luminescence photons emitted by stimulation with a NeHe laser. |
|
| The light emission is detected by a photomultiplier tube and the results are calculated for each sample. |
|
| Spectrometer for the analysis of ferrous and non-ferrous alloys on a photomultiplier optical basis. |
|
| The photomultiplier tube is an enhanced version of the photocell, which was first used by astronomers to record data electronically. |
|
| Application of a voltage to the electrode then induces chemiluminescent emission which is measured by a photomultiplier. |
|
| The three BIPM preamplifiers have been also replaced by commercial fast preamplifiers designed for the new photomultiplier bases. |
|
| The signal was isolated from the excitation laser beam with a glass filter and a pinhole, detected by a photomultiplier tube, and recorded by a digital oscilloscope. |
|
| First measurements have shown the validity of the experimental set-up although improvements to protection from stray light, distance adjustment and photomultiplier matching are needed. |
|
| Rubidium's photoemissive properties have led to its use in night-vision devices, photoelectric cells, and photomultiplier tubes. |
|
| They are also used in scintillation counters, which contain a material that produces flashes of light when struck by X rays or gamma rays, coupled to a photomultiplier that counts the flashes and measures their intensity. |
|
| The system is equipped with a CCD array detector for rapid data acquisition and a photomultiplier tube for high sensitivity across the visible spectrum and with a near-IR detector extending the wavelength range to 1700 nm. |
|
| Thus, measuring the light pulse with a photomultiplier tube can allow the accumulated radiation dose to be quantified. |
|
| Hamamatsu Photonics is one of only two companies worldwide still in the photomultiplier tube business and leads this market by a significant margin. |
|
| A photomultiplier tube consists of a photo-emissive cathode and a series of dynodes in an evacuated glass enclosure. |
|
| These devices include photodiodes, photomultiplier tubes, scientific light sources, infrared detectors, photoconductive detectors, and image sensors. |
|
|
|
| In operation, two detectors, a Photomultiplier Tube and a lead-sulphide photoconductive sensor, are illuminated alternately by the sample and the reference beam. |
