Fresnel Lens

Microoptics is one of the applications for multi‑photon polymerization (MPP) technology. Using this technology, polymeric structures with a resolution of hundreds of nm can be obtained. Due to the accuracy of the technology, micro-optical structures of complex shape such as Fresnel lenses can be fabricated. In this way, a Fresnel-like lens with a varying aspherical profile can be produced. The illustrated lens has a diameter of 500 µm. Superb nearly spherical aberration-free focusing can be obtained in each Fresnel zone. Microoptics can be used in various optics and photonics applications
for the purpose of miniaturization.

Multi-Photon Polymerization

Microfabrication by multi-photon polymerization is a direct laser-write technique which allows 3D structuring of photopolymers at the micro- and nano-scale.

Laser Nanofactory

Multi-Photon Polimerization

Multiphoton-polymerization (MPP) is a technology that enables the production of arbitrary shape polymeric structures within submicrometric resolution. First, a photoresist sample is prepared by drop-casting polymer material mixed with a photoinitiator on the glass slide and then pre-baking.
