TRK1

Tracking Auto Focus Depth measurement unit

TRK1

Tracking auto focus system for depth measurement with microscope/AF image processor package Built-in detection target mark with lighting 2 projected circle patterns on actual image objects for detection of focal points to calculate the center of the gravity Tracking AF by controlling the stage motor of microscope to hold the focal points
