Shrinking the sensor modules dimensions raised new challenges for the auto-focus actuators. Nowadays, voice coil motors and piezzo motors are the main technologies used. Both of them have some advantages and some drawbacks. At MMS we have comprehensive experience with both technologies in terms of production quality and driving methods to achieve the best possible performance and accuracy.
Proven with AF motors from vendors like Sharp, KMOT, Toshiba, Samsung and others, MMS technology guarantees stable operation in all working conditions, excellent focus accuracy and speed.
