High Precision Camera Module Active Alignment System

MD-90AA Pro Series provides full-function, automatic and high precision active alignment capability for camera module assembly. Whether by applying 6-degree freedom AA on Senor or 5-degree freedom AA on Lens based on MTF calculation, the image quality of camera module is effectively improved. With loop-rail conveyer design, this system can be easily integrated into automatic production line and, therefore, greatly improves production efficiency.

• Full-function and digitalized image quality alignment. Optimize image quality by applying 6-degree freedom Sensor AA or 5-degree freedom Lens AA adjustment.
• To satisfy alignment requirements of different kinds of camera module such as Sport Cam, IP Cam and Automotive Cam.
• High-speed image plane tilt correction and center alignment by conducting αβ axis adjustment and XY axis centering.
• Thoughtfully designed jig for quickly and easily model switching that can fulfill the demands of variety type but small quantity product; it also can be customized.
• The Loop-Rails structure is designed for increasing the manufacturing speed and integrating with automatic In-line production.
