Micro-lenses offer a long focal depth, which means that an array can project a focused image on to a parallel, slanted or curved surface.
Micro-lens arrays may be configured to provide a bright output in an extremely low-profile form factor. In conventional projector technology, the higher the brightness required, the larger the projector. By contrast, micro-lens arrays can be arranged next to each other so that their images overlap to create a brighter picture, while the thickness of the projector, typically 3mm, remains the same.
Micro-lens array technology from ams is in use in the automotive sector and in various non-automotive applications.
