Phantom fabrication using two-photon polymerization

For the validation of optical microscopes, such as laser scanning microscopes (LSM) or short coherence tomography (OCT) devices, microstructured phantoms are ideally suited. At ILM, two-photon polymerization is used to create phantoms with specified

structures in the micrometer range. With the aid of a suitable 3D nanoprinter, different phantoms can thus be printed with submicrometer accuracy and object sizes in the millimeter range.

Example phantom

Microstructured phantom (total size: 1 mm X 1mm X 0.2 mm) made of parallel cylinders with diameter of 10 µm.
