WDI’s ATF2-LV is a high speed, high accuracy, autonomous digital autofocus sensor system. Its “Smart Sensor Architecture” (SSA) incorporates a semiconductor laser, built-in CMOS image sensor, FPGA and microprocessor for fast digital image processing. By projecting a laser dot onto the sample and digitally processing the image, the ATF2-LV brings the microscope quickly to close vicinity of final focus. The sensor then refines focus using image contrast analysis.
