Inspection/Measurement
MATSUNAMI has various methods to inspect our final productions in order to secure our quality.
In response to each company's requirement, we apply various tests such as environmental test, complicated shape measurement, spectrum measurement and etc.
In addition, visual inspection addressed in our clean room enable us to deliver our products (CMOS and other sensor cover glass) without defects more than 3μm level. Various visual inspection standards are set at MATSUNAMI.
