image photon counting system, IPCS
An electronic detector system that has contributed to the knowledge of astronomy.

This detector is a four-stage, magnetically-focused image intensifier, coupled via a lens to a plumbicon television camera tube.

A plumbicon is the development of the vidicon television camera tube in which the photosensitive material is lead oxide.

A plumbicon is a registered trademark of Philips for its Lead Oxide (PbO) target vidicons or camera tubes in which a charge-density patterns are formed by photoconduction and stored on photoconductor surfaces that are scanned by electron beams; usually, of low-velocity electrons; used chiefly in industrial television cameras.

image tubes
An image intensifier which is a form of electron tube in which an image is focused onto an input photocathode.

The resulting emitted electrons are accelerated within the evacuated tube by a very high voltage.

Image intensifiers are used in many instruments; such as, cameras, spectrographs, and acquisition and guidance systems.
