-- Inkron, a Nagase Group Company, the global leader of siloxane-based, optically clear Nano-Imprint Lithography (NIL) materials, makes a strategic investment in NIL materials and components development infrastructure. The investment will significantly accelerate Inkron's development of high-performance optical materials needed in critical components of augmented reality (AR) glasses, 3D sensors and other diffractive optical elements (DOE). Inkron's ability to provide its customers with customized optical NIL materials with fast turnaround time and enhanced performance shall be significantly improved with this investment. Now Inkron can also provide component prototyping and small series manufacturing services for its customers.
The cornerstone of the investment is the purchase and installation of an EVG®7200 automated UV NIL system from EV Group (EVG). The EVG 7200 system leverages EVG's innovative SmartNIL® technology and materials expertise to enable mass manufacturing of micro- and nanoscale structures with unmatched quality. The system provides low-force and conformal imprinting, fast high-power exposure and smooth stamp detachment with unmatched throughput and low cost of ownership. The EVG 7200 system with SmartNIL technology is ideally suited for volume production of next-generation photonic devices including waveguides and DOEs, for applications such as AR and virtual reality (VR). In addition to these features, the tool that has been shipped to Inkron includes a high-intensity UV station, heated chuck and support for soft-UV-NIL for microlens molding applications.
Inkron offers NIL processable materials in a broad index of refraction (RI) range even up 2.0. The NIL materials are complemented with overcoat, gap fill and planarizing coatings with RI as low as 1.1. The combination of these material platforms and the EVG 7200 system provide an ideal infrastructure for novel optical component development with accelerated turnaround time while enabling careful optimization of the resins and the process for specific devices. In addition to the NIL equipment, Inkron has made and continues to make significant investments in optical structures manufacturing and testing equipment, including device performance and reliability testing. A dedicated team has been established to support the Inkron NIL ecosystem with material scientists, lithography process engineers and photonics experts, headed by VP Dr. Janne Kylmä. The commercial side of the NIL activities are directed by Inkron VP Operations Mr. Jukka Perento.
