Advanced Optical Imaging (ADIMA)

Important results from the project

Development of optical systems is in a transition period when classical lenses are about to be replaced by advanced diffractive optics. A regular camera module often consists of up to six different classical lenses. An equivalent system based on diffractive optics requires only flat optical elements with advanced surface topography. NILT Sweden Filial is one of the leaders in manufacturing of advanced diffractive lenses and the ADIMA project has strengthen NILT’s competences and market presence significantly.

Expected long term effects

NILT is today in dialogue with several leading phone manufacturers about making their camera modules more efficient by using diffractive optical elements. Since the start of the ADIMA project, NILT Sweden Filial has grown from 4 to 6 employees and NILT has expanded its competences within optical design and measurements.

Approach and implementation

In the ADIMA project, NILT Sweden Filial has focus on the development of advanced nanostructured silicon DOE masters. To reduce the price of the optical elements, the expensive silicon masters have been replicated in plastics. The project plan has been followed and the technical and marketing goals have been achieved.
