NanoScribe GT2

The NanoScribe GT2 Laser Lithography System is a state of the art two-photon polymerization volumetric maskless printer. It can create three-dimensional nanostructures using a NIR femtosecond laser via direct-write onto a photosensitive resin that is subjected to a non-linear two-photon absorption process. This process involves cross-linking the resin via UV absorption. In essence, the laser sets a focal light cone where a concentration of the light intensity defines the exposure focal spot volume or a “3D Pixel”. Using this technique a CAD design can be broken into and X, Y, Z coordinate system to define the structure pixel by pixel and layer by layer.

The exposure side of the system sits in a fine-tuned vibration isolation table and a high-speed ultra-precise piezoelectric stage for movement in x-y-z, and finally a galvanic mirror defection system for focusing and beam rasterization. Models for printing can be designed using the stand-alone software DeScribe which comes with the tool or with any CAD software capable of outputting DXF or STL file formats. The DeScribe software can import these formats. CNF has 3 Solution sets for particular scales and applications.
