Zusammenfassung:	An infrared photoelectric tube inspection apparatus includes a probe which carries along the tube one or more infrared emitters and a plurality of infrared detectors. A cylindrical sleeve encircles a portion of the probe and has resilient fingers slidably frictionally engageable with the inner surface of the tube for centering the probe, equiangularly spaced-apart slots being formed in the sleeve to accommodate light transmission therethrough. Fiberoptic bundles in the probe have their inner ends optically coupled to the emitters and detectors. Preferably, each emitter is modulated for eliminating the effects of ambient light.
