摘要： The present invention relates to an auto-focusing optical system, and more particularly, to an auto-focusing optical system for a camera module, capable of obtaining a high resolution in a small size using a liquid lens whose curvature is varied depending on an applied voltage. In the auto-focusing optical system, a first lens group has a liquid lens whose curvature is varied and having a plus optical power, a second lens group has a plus optical power, and a third lens group has a minus optical power. Thanks to an auto-focusing optical system including a liquid lens according to the present invention, not only a manufacturing in a small size is possibly realized but also a high resolution can be obtained, and power consumption is small.
