Specialized - Photo Tube ·Photomultiplier
AEI photoelectric device documented with manufacturer ratings and characteristics. The available source establishes optical detection service, but the extracted description does not expose enough construction detail to classify it more narrowly than a general phototube.
27M13 PhotoTube; full semantic REDO from printed ratings and characteristics.
