Nanoscribe unveils production process at SPIE West

The production process of microlens arrays, based on a 2PP printed polymer master and subsequent replication processes. The figure shows the process steps for injection molding.

Nanoscribe’s new Photonic Professional GT2 3D printers change the way to produce micro-optical components. This additive manufacturing technology enables the fabrication of ultra-precise micro-optics as polymer masters for serial production, which are needed, for instance, in mobile or augmented reality devices, for sophisticated sensors or advanced solutions in healthcare and automotive industry.

At the upcoming SPIE Photonics West, the leading trade fair in optics and photonics, Nanoscribe presents the entire process chain for series production of micro-optics based on 3D printed polymer masters as starting point (booth 366, South Hall). Up to now, the production of innovative micro-optical designs has been challenging due to very high demands with respect to shape accuracy and low surface roughness required for optimum optical performance. Furthermore, product development processes have to cope with the ever-increasing importance of rapid innovation cycles and low costs for serial production.

Based on the powerful technology of two-photon polymerization (2PP) Nanoscribe’s 3D printers transform digital models directly into physical objects with submicron resolution.
