  • Dear Customers


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.


●Clean room overview: 1000 class level (10 Class level for clean booth)
●Inspection method for glass surface and interior
・ High-brightness light inspection for micro defects (10,00 ~300,000 lux)
・ Visual inspection with fluorescent lamp (600~8,000 lux)
・ Microscopy inspection
・ Automation inspection line
・ CCD image inspection
●Inspection method for glass interior, pulse defect, surface unevenness
・ Image inspection(Collimator lens)
・ Xenon irradiation test
・ Strain inspection
