Narragansett Imaging

Narragansett Imaging is the only company in the world that still manufactures plumicon tubes. They still manufacture plumicon tubes for medical imaging but have long discontinued making any for broadcasting. They still have inventory of old broadcast tubes and some that can be cross referenced.
I personally believe plumicon tubes had a certain dimension that CCD cameras in the late 80s could not duplicate. Yes tubes could get burn in,consumed much more power, high maintenance with registration, cameras were heavy and needed frequent alignments. However when setup and aligned with new/low hour tubes plumicons just looked amazingly life like, with really nice color saturation than the CCDs did back then, which have now been replaced with current CMOS echnology. The fact that they are still manufactured for high end imaging says a lot.
