High magnification surface defect inspection system (magnifying magic mirror)

product02-item02

It is a high magnification inspection device of YIS series and displays a field of view of 10 mm on the monitor. It is widely used especially for inspection of slip lines occurring after epi processing. It is also effective for surface inspection of hard disks and optical polished parts. The detectable sensitivity is 50 times magnification of the Nomarski microscope.
