Z-Axis Focusing Beam Brush Device and Associated Methods

Our fifth-generation device to rapidly control the focus or divergence. Unlike previous systems which are generally around 10 times slower than X-Y scanners, this device is just as fast as a scanner, because it uses a scanner as the heart along with low-inertia moving member to achieve focus changes.

Scanning Mirror System and Associated Methods

X-axis scanning mirror that is shaped like Darth Vader’s helmet, so as to have the same inertia as Y-axis mirror. When both X- and Y-axis mirrors have the same inertia there won’t be any phase difference during vector scanning. Our Darth-Vader-Shaped mirror does a much better job than using two Y-axis mirrors as many competitors do…
