An ideal projection optical module has perfect focus uniformity – that is, the entire image is in focus at the same time.
If an optical module has a focus non-uniformity problem, then the image is visibly out of focus in at least one location, often the edges or corners. Focus non-uniformity can be caused by variations in optical component performance or optical misalignment.
