As seen above, this barrier used in conventional Gen III tubes, prevents damage to the photocathode coating by shielding it from ions backscattered from the microchannel plate (MCP).
Night vision technology update: recent international developments in night vision technologies have followed the twin paths of image intensification (12) and thermal. One significant change in recent years, however, has been the convergence of these traditionally separate paths as manufacturers work on a range of developments targeting the tactical `fusion' of both 12 and thermal images.
