Two-Photon Line-Illumination Temporal Focusing Micro-Nano 3D Printer
LINESCAN 100i

The LINE SCAN-100i system utilizes the cutting-edge Line Illumination Spatiotemporal Focusing(Line-TF TPL) technology to achieve true continuous 3D nanofabrication. Through full-bandwidth data streaming and pixel-level grayscale control, the printing throughput is increased by 12.7 times compared to traditional parallel techniques. This technology completely eliminates stitching defects and achieves sub-diffraction-limit precision with lateral75 nm and axial 99 nm resolution over centimeter-scale areas, providing core driving force for industrial applications in micro-optics, metamaterials,and biomedicine.
