Optimization of a mobile phone camera for as-built performance

The work presented here shows a compact lens system that demonstrates improved imaging quality performance while focusing on as-built performance and design for manufacturing. Using Zemax, we consider an approach for optimizing for as-built performance and incorporate the approach into the design process for a mobile phone camera. The optimized design consists of 6 plastic aspheric lenses, an infrared glass filter, and a 12 MP CMOS image sensor. The optical system demonstrates high-resolution imaging and has a field-of-view of 87.6 degrees, an F-number of 2.0, a maximum distortion of less than 2.5%, and a total track length of 6.630 mm.
