The instinctive reaction when measuring nuclear radiation is to think of a Geiger counter, as the low-pressure gas tube detectors have entered our popular culture through the Cold War. A G-M tube ...

Hamamatsu Photonics introduces its G1719X series of InGaAs Photodiodes: compact, surface-mounted NIR sensors with low dark current designed for infrared applications, including gas sensing, laser ...

Enhancing the efficiency of infrared sensors like photodiodes could bring significant benefits across these applications. The new device is compatible with existing production methods, making it ...

For the last eight years, a team of researchers at Aalto University in Finland has been working to improve the efficiency of photodiodes, a type of infrared sensor that converts light into ...

Ceci conduit à un autre type de photodiode : les photodiodes PIN. Le courant d'éclairement du phototransistor est donc le photocourant de la photodiode collecteur-base multiplié par le gain β du ...
