Often on mobile phones the weak link in the cameras that are built in are the cheap plastic lenses and optics. A company called Nemotek is demonstrating a new wafer-level camera lens at MWC that is designed for ultra-slim mobile phones.
The VGA wafer-level camera is called the NEMO-02VG and uses replicated lenses on glass to deliver a reliable solution able to withstand "intense" environmental conditions. The camera uses an infrared filter and apertures are built-in to reduce the number of elements within a camera module.

The integrated design makes the camera lens and its associated module thinner allowing the camera to be used in thinner handsets. The two-element lens has two optical wafers that are processed separately and bonded together before being diced. The process gets around the technical challenges of bonding and dicing two glass wafers together. The camera is being shown off at MWC.
