Nightvision tube module simplification

An image intensifier assembly has an image intensifier tube having a optical element. The optical element includes a emitting surface. The optical element comprises an outer dimension. The image intensifier assembly further includes a first 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 surrounds the outer dimension of the optical element. The first outer dimension is within the image intensifier assembly. The first circuit board further includes a component surface. The component surface extends from the first inner dimension to the first outer dimension. The first circuit board has power supply components mounted on the component surface.
