WebA photodiode, also known as a photodetector, photosensor or light detector, is a semiconductor device that converts a light signal into a current signal. When a photodiode absorbs photons having sufficient energy, it generates a current linearly proportional to the irradiance under a specific spectrum. WebLaser light can be emitted in a tight beam that does not grow in size at a distance from the laser. This means that the same degree of hazard can be present both close to and far from the laser ...
