Applications

Automate inspection across your R&D and production lines

Automated Optical Inspection (AOI) is one of the most efficient forms of device inspection, but it is typically limited by resolution. Nanotronics AI detection algorithms overcome this and detect defects that would otherwise go unnoticed.
