Customer Product Design (based on TLens)

Offentlig prosjektsammendrag

The mobile phone market is highly dynamic and the requirements for the auto-focus (AF) lenses become tougher every year. They need larger optical aperture and deliver higher optical power, while maintaining the image quality. There is a trade-off between these requirements, and we need to find original solutions in terms of lens architecture and processing. The targets of this project are to simulate, design and produce an AF TLens Platinum with increased image quality and higher mechanical robustness (starting from the Platinum lens developed in the previous couple of years). Very small size and low cost are compulsory requirements for components to be integrated in mobile phones. This has to be accomplished without compromising the optical performance and the long-term reliability. The requirement for manufacturability in very high volumes adds to the challenges. The design concept proposed earlier is implemented into prototypes. After their characterization, the design model will be validated and calibrated. Solutions for improved performance need to be found, by modified design, processing and/or component materials. Materials and processes that are new and challenging for such applications will be searched for and tested, to ensure improved mechanical robustness already at the wafer level. Challenges are also related to finding suitable characterization methods for such a purpose. A new packaging has been developed for TLens Platinum. It consist of a plastic frame and a flexible board for electrical connections to the camera module. The concept remains to be tested, validated for manufacturing, and proven reliable. If required, design changed will be implemented. New-generation prototypes will be fabricated. Extensive functional and reliability testing will be performed.
