Nightvision tube module simplification

A method of assembling an image intensifier assembly, the method comprising:

• placing an image intensifier tube in a package, the image intensifier tube having a optical element, the optical element having an emitting surface, the optical element having an outer dimension;
• disposing a first power supply around the optical element outer dimension, the power supply comprising a first circuit board having a first inner dimension defining an opening, a first outer dimension and a first thickness, the first inner dimension surrounding the outer dimension of the optical element, the first outer dimension within the package, the first circuit board further having a component surfaces, the component surface extending from the first inner dimension to the first outer dimension, the first circuit board having power supply components mounted on the component surfaces,
• wherein the first power supply is electrically coupled to the image intensifier tube to operate the image intensifier tube.
