专利汇可以提供Light amplifier device having an ion and low energy electron trapping means专利检索,专利查询,专利分析的服务。并且A light amplification device such as an image intensifier or low level sensing device is disclosed which includes a photocathode spaced from an aluminized target electrode and a microchannel plate intermediate said cathode and target. A thin non-selfsupporting substantially optically transparent layer of material of a substance and thickness so as to be essentially transparent to high energy electrons, on the order of 100 to 1,000 electron volts, and light is situated atop the front end of the microchannel plate, covering the passages therein, in order to trap ions, which otherwise would travel to the photocathode, neutral gas ions, and to absorb scattered low energy electrons generated by secondary emission at the rim portion of the individual tubes in said microchannel plate, which would otherwise travel into the microchannel plate passages and to pass any light which passes through the photocathode and transmit any light which penetrates through the photocathode. The microchannel plate is spaced by a predetermined first distance from the photocathode, with its covered end facing the photocathode, and is spaced by a second distance, larger than the first distance, from the aluminized target electrode. A first voltage is applied between the photocathode and the microchannel plate and a second voltage, at least twice as great as the first voltage, is applied between the microchannel plate and the target electrode, and a third voltage is applied across the microchannel plate.,下面是Light amplifier device having an ion and low energy electron trapping means专利的具体信息内容。
