ATF5CM Laser Tracking Auto-focus Sensor for TFT Cell/Module Repair
Specifically to facilitate cell/module repair, the ATF5CM forces microscope to automatically focus on the surface of the glass where the TFT array is deposited (usually the bottom). This process will not be distracted by reflections from other surfaces within the light path such as the protective film, the polarizer or the glass.
