Specialized - Photo Tube ·Photomultiplier
Grid-controlled sixteen-stage multiplier phototube available with S-1, S-11, or S-20 photocathode response. Its long dynode chain provides high optical gain while the control grid permits additional modulation of the detected signal.
Grid-controlled multiplier phototube with selectable S-1/S-11/S-20 photocathode and 16-stage electron multiplier.
