A G-M tube is not the only game in town though, and even the humble photodiode can be pressed into service. [Robert] gives us a good example, with a self-contained radiation detector head that ...

The basic concept of the detector is to build a light-tight test ... the putatively phosphorescent compounds within. A high-speed photodiode is then used to detect the afterglow, which can be ...

Researchers at Aalto University have developed a new type of infrared photodiode that is 35% more responsive at 1.55 µm, the key wavelength for telecommunications, compared to other germanium ...

Multiple photodiode detectors are used to track the transit of dye-labeled single lipids through an excitation spot at high resolution. One of the challenges of working at the cutting edge of ...

Marktech Optoelectronics is one of the world’s leading manufacturers of LED emitter and photodiode detectors with a spectral range from 235nm to 4.3 microns. Light sources include UVC LEDs, UVB LEDs, ...

They are used in TV and AC remotes, heart rate monitoring devices, barcode scanners, motion sensors, smoke detectors, etc. The Aalto University team has developed a photodiode that is 35 percent ...
