IR filter for old home tube camera question
A lens filter question. I have a 1978 RCA CC002 striped vidicon home color video camera with a gone-to-cloudy IR filter behind the lens...a common problem with the light blue fluorite material they used. 11mm x 15mm and long gone from anywhere. Without it, the camera focus goes bad and a massive red tint appears. Too much IR in the wrong focus hitting the tube. I can find 58mm filters for the front. Does it make a difference if the filter is in the front or does it need to be in the back of the optical path? When this thing works, it is a great 1978 image and easy to tune with a scope.
