Nemotek Technologie, a manufacturer of customized Wafer-Level Cameras for portable applications, launched its first two-element VGA wafer-level lens in mid-February 2010 at the Mobile World Congress in Barcelona, Spain. The two-element lens utilizes glass wafers instead of traditional plastic to provide an advanced camera lens design with lower distortion, better resolution and higher image quality. Nemotek utilizes replicated lenses on glass as an alternative to the multi-element plastic lens, to deliver a reliable solution that can withstand the most intense, environmental conditions. The lens structure also incorporates an infrared filter and apertures so as to reduce the number of components within a camera module and assist in the development of ultra-slim handsets. “With the two-element lens we are providing a smaller and compact form factor that utilizes the advantages of wafer-level technology and improves the overall image quality for cameras,” said Jacky Perdrigeat, CEO of Nemotek Technologie. The two-element lens is made up of two optical wafers that are processed separately and then bonded together before being diced. Thanks to this pair of lenses, Nemotek overcomes the technical challenges of aligning, bonding and dicing two glass wafers together.
