3D microfabrication technology
The high-precision 3D printing of lenses is performed on our Nanoscribe Quantum X Align tool. This additive manufacturing process offers many advantages over traditional, subtractive, methods of creating lensed or tapered fibers, such as:
- High positioning accuracy relative to the fiber core.
- Full control over lens design parameters, such as asphericity for aberration correction.
- The ability to print directly onto existing surfaces, enabling more options for light coupling.
