A faceplate of a thin-window photographic recording tube including a bulb face having provided therein a straight slit extending longitudinally of said bulb face. The faceplate features increased mechanical strength to withstand the atmospheric pressure and improved adhesion to the bulb face. The bonding agent for fastening the faceplate to the bulb face is advantageously isolated from the slit.
An electron-optical cathode ray tube has a face plate comprising a fiber plate to achieve image receiving and a clear glass plate to achieve image transmission, the glass plate being positioned at a retracted position relative to the fiber plate, whereby image transmission and receiving can be effected. This is a continuation of application Ser. No. 147,807, filed May 28, 1971, now abandoned.
