  • 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 ...

  • Ultraviolet Reflectance Imaging: Applications |

    Is it possible to image a UV laser with a Silicon Sensor CCD camera offered by Ophir-Spiricon? The answer is yes, but the direct UV light ablates Silicon CCD chips over time. The ablation is cumulative and depends on the intensity, the wavelength, and the duration of the light on the sensor. The best choice for imaging UV light without damage is to avoid directly imaging the beam on the CCD ...
