How To Use photocathode In A Sentence

  • The quantum efficiency of the photocathode decreases significantly at 830 nm creating an effective acceptance bandwidth of 650-830 nm in fluorescence detection.
  • The photocathode in the night scope that converts visible light into electrons is sensitive to both visible light and some infrared radiation.
  • If excitation light rejection at the photocathode were not an issue, this might simply require an increased integration time or gain setting to acquire a sufficient fluorescence signal for processing.
  • The long-pass and band-pass filter combination was used in these studies at each target depth, and the integration time was varied between 200 and 700 ms because the amount of light collected at the image intensifier photocathode varied.
  • The output from the metal channel dynode chain is a current proportional to the number of photons striking the photocathode and to the voltage drops along the dynode channel. Undefined
  • Auto gating BSP power supply is adopted to extend dynamic range, protect photocathode and microchannel plate.
  • On the one hand, ICCD extends the spectral response, through proper input window and photocathode, from visible light to X-Ray, ultra-violet and near infrared for different applications.
  • Ultraviolet sensitive photocathodes are also used in cameras in rocket and balloon - bome experiments.
  • Reflections from the target were focused on a converter unit containing a photocathode, which provided the viewer with a reconstructed image.
  • On the one hand, ICCD extends the spectral response, through proper input window and photocathode, from visible light to X-Ray, ultra-violet and near infrared for different applications.
