Purpose and goal

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 wants to take the next step in quality to be able to replace classical lenses in optical imaging systems for cameras and mobile phones.

Expected results and effects

The latest revolution in the camera market was replacing the analog image recorder with a digital CMOS chip, and the digital camera was born. The next leap in the development of camera systems will be in replacing the classical lenses with digital diffractive optical elements (DOE) which will make it is possible to reduce weight, size and cost which are key factors for many applications. The mobile phone market, which already has managed to shrink the cameras a lot are one of the drivers and early adopters of the imaging DOE-technology.

Planned approach and implementation

NILT Sweden Filial has many years’ experience of nanostructuring with focus on nanoimprint lithography. In the ADIMA project, NILT Sweden Filial will focus on the development of advanced nanostructured silicon DOE masters that will be fabricated in a cleanroom environment. To reduce the price of the optical elements, the expensive silicon masters will be replicated in plastics.
