An apparatus for aligning a lens module with an image sensor to form a camera module includes a chart holder, a positioning unit and a reflective elements holder assembly. In use, the chart holder holds a test chart having a region of interest (ROI), the positioning unit holds the lens module and the image sensor, and the reflective elements holder assembly holds multiple reflective elements between the chart holder and the positioning unit. A first optical path from the ROI is directed to a first position on the image sensor. Second optical paths from the ROI are reflected by the reflective elements to respective second positions on the image sensor, the second positions being spaced from the first position. The images captured by the image sensor (arising from the aforementioned optical paths) are analysed and the positioning unit aligns the lens module with the image sensor based on such analysis.
