  • Light Detector - an overview | ScienceDirect Topics

    Light detectors are designed to convert low light levels into an electric signal of reasonable amplitude to avoid deterioration of the signal by external noise or pick-up. To ensure a high-quality signal, a light detector must fulfill three main requirements: • A high quantum efficiency to transfer as many of the photons as possible into charge carriers to ensure a high signal amplitude. The ...

  • Laser Photodiode Sensors | Ophir Photonics

    Photodiode sensors have a high degree of linearity over a large range of light power levels: from fractions of a nanowatt to about 2 mW. Above that light level, corresponding to a current of about 1 mA, the sensor saturates and reads erroneously low. Therefore, most Ophir PD sensors have a built-in and removable attenuator allows measurement of up to 3 W without saturation.
