Cell phone camera

Development of the entire optomechanics

Camera for cell phone with moving lens assembly.

The camera is used in a cell phone with 5 and/or 8 MBit sensor. Important development requirements included the overall size and a simple installation concept. However, the accuracy requirements for the lens movement during focussing have to be met. Cost requirements for manufacturing and assembling have to be accomlished.

CEMEC service

Simulation of forces and deformations when moving the lens assembly.

CEMEC supplied the concept and complete development of the mechanical parts, including integration and design of the flexible circuit board with sensor and controller. The services package was rounded out by FEM modelling to ensure the accuracy of the focussing movement, prototyping and implementation support.

CEMEC manufacturing
