This is the beginning of my detailed investigation into the viability and theory behind my quest to find a way to enhance the cutting capability of the normal single lens system that everyone uses.
This is a theory session and looks at the potential weak spots in lens theory that I believe can be exploited to benefit cutting efficiency . The dream is to double the cutting capability without replacing the laser tube. This dream is based on initial trials and pragmatic evidence but this session tries to explain what I have seen so far by exploring the way in which lenses work.
