BEGIN ARTICLE PREVIEW:

Nanoscribe introduced the new IP-n162 photoactive resin, a printing material with special properties for micro-optical elements such as microlenses, prisms, or complex freeform optics. The new photopolymer resin features a high refractive index in combination with a high dispersion, which corresponds to a low Abbe number. These properties are particularly beneficial for the 3D Microfabrication of innovative micro-optical designs, even without rotational symmetries, and for compound refractive optical systems with three-dimensional shapes and more than one refractive surface. With a low absorption in the infrared region, the photo resin is the best choice for the fabrication of infrared micro-optics, but also for applications where low absorption losses are critical such as optical communication, quantum technology and photonic packaging.
The novel printing material is specifically designed for additive manufacturing based on Two-Photon Polymerization (2PP) in a straightforward 3D printing workflow. The high refractive index material enables innovative micro-optical designs with high shape accuracy and takes high-precision microlenses and freeform 3D micro-optics to the next level.
Thanks to their optical properties, high refractive index polymers facilitate a variety of applications related to disruptive technologies. For example, in optoelectronic applications, they enhance the visual properties of display devices or camera and projector lenses. …
