Which Sensor is the Best for Confocal Imaging?

WebNov 1, 2006 · Recycling of the photons that pass through the semi-transparent photo-cathode without kicking out of an electron by the PMT input chamber (increasing the reflectivity of the surrounding parts). • By special tuning of the thickness and composition of the photo-cathode for optimal interaction with light, by application of new processes. • WebH7827-001中文资料. The H7827 series photosensor modules incorporate a 19-mm (3/4") diameter head-on photomultiplier tube, a high-voltage power supply circuit and a low noise amplifier. Two types of amplifiers are available with a current-to-voltage conversion factor of 1 V/µA or 0.1 V/µA and a frequency bandwidth of DC to 20 kHz or DC to ... dry cathode 4680

How do we calculate PMT bandwidth? Forum for Electronics

WebPhotonis PMT Basics - University of Chicago WebApr 1, 2009 · I think, the above explanation isn't exactly correct. Clearly the signal rise/fall time defines the signal bandwidth. But it's related to transit time in so far, that the transit time dispersion is one main source of non-zero rise/fall time. This strongly depends on field unformity and possible electron pathes with a particular PMT design. WebThis consideration explains the peculiarities of PMT signals and gives hints to handle these signals. The PMT A conventional PMT (Photomultiplier) is a vacuum tube which contains a photocathode, a number of dynodes (amplifying stages) and an anode which delivers the output signal.
