Macnica ATD Europe distributes the new AF Explorer kit (AutoFocus) of Corning, a platform realizing Auto Focus based on Varioptic Liquid Lens technology. It consists of several PCB boards with associated software. The kit is best suited for camera developers who want to evaluate and study characteristics of the liquid lens and can also be proposed as a reference design. It has been developed around the Cypress CX3 chip and a specific ISP. It is based on an MIPI pipeline between sensor, ISP and embedded host. Several types of sensor boards and liquid lens modules are supported while the default configuration includes a Sony IMX335 5MP sensor and the Varioptic C-S-25H0-075 liquid lens S-mount module. The kit is fully compliant with the USB interface standard.
