The Helicon Focus Key can be designed in various configurations, including transmission and reflection modes. In transmission mode, the device uses a transparent substrate with a helical phase structure etched onto it. In reflection mode, the device uses a reflective substrate with a helical phase structure.
The workflow is deceptively simple, yet maddeningly precise: helicon focus key
A Helicon Focus Key is based on the concept of helicon waves, which are electromagnetic waves with a helical phase structure. These waves have a unique property: they can be focused to a very small spot size, creating a high-intensity beam. The Helicon Focus Key uses a specially designed optical system to generate and control these helicon waves. The Helicon Focus Key can be designed in
