Abstract
An image converter is fabricated by processing its photocathode within an evacuated chamber free of harmful contaminants. The evacuated chamber, in turn, is housed along with the remaining structural components of the intensifier in a further closed chamber that may be evacuated at the proper time in the fabricating cycle. The proposed photocathode is released from its enclosing chamber for only that short period of time required to effect a transfer from that chamber into mating engagement with the remaining envelope portion of the intensifier. When these components have thus been assembled, they are integrated to complete the device.
