Non-contact 3D Shape Measuring Device Mitaka Kohki｜possible to measure the surface shape without having to replace the workpiece from a small area to a large area.Measure workpieces with steep angles and reflectivity independent with a high resolution of 1nm.

this device is based on an optical microscope and uses a tracking type autofocus with its own AF sensor.High precision measurement from a small area corresponding to stage movement.Completely non-contact type,ideal for non-contact roughness measurement （line roughness、surface roughness）and step measurement.
