    Good day gentlemen.

    I have a question to ask all of you. I have been very interested in night vision technologies and I wish t ask some of you for help.
    I am trying to create a passive night vision. The kind that uses image intensifier, but here is the problem. The intensifier consists of a photocathode that turn light into electrons, a microchannel plate that is used to amplify the electrons discharged from the photocathode and a phosphorus screen that is used to catch the many electrons and turn them into light.
    Now my question is how can I make these 3 important parts if its even possible for an average person?

    One part you have left out is the very high vacuum. You could go to outer space to collect some.

    In terms of manufacture, it will be somewhat more complex than this.

    (Note they manufacture a vacuum rather than going out and collecting some.)
