UMA / PRODUCTS / Camera Module Image Tester


Camera Module Image Tester

• The digitalized quality full inspection of camera module can be achieved by through three stations test, intrinsic calibration, Image Quality and Resolution, with multiple test items of each station.

• The maximum FOV(Field of View)is close to 215 degree for fulfilling the test requirements of different kinds of camera modules such as surveillance, sport and in car, etc.

• Two tracks transportation system design allows operating subjects load/unload while testing for reducing the total cycle time.

• Fast tray and Jig switch design can meet small-volume and variety of models production requirements. This system also can be customized for following client’s production line plan.
