相機模組影像測試儀
Camera Module Image Tester


產品特點Features
透過三個測試站,本質校正、影像品質與解像力等多種測試功能可對像機模組進行全功能之數位影像品質檢驗。 
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.
●FOV(Field of View)最大值可接近 215°,可滿足各式相機模組的需求如運動相機、網路相機、環景相機與車用相機等。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.。
●雙軌運輸設計允許測試過程中進行樣品取放,以達到降低測試週期的功能。Two tracks transportation system design allows operating subjects load/unload while testing for reducing the total cycle time.
●快速切換治具與料盤設計,可滿足少量多樣需求;也可配合客戶產線客製規劃。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.
