ABSTRACT:
The present invention involves a method for simultaneously applying an activation layer on the photoemissive layers of a plurality of photocathodes such as those used in image intensifier devices. The method includes the steps of diffusing a flux of activating chemicals over the plurality of photocathodes, wherein the flux is substantially spatially uniform with respect to the plurality of photocathodes; monitoring the sum photoresponse of the plurality of photocathodes; and terminating the flux of activating chemicals when a desired sum photoresponse is attained.
