* Inspection Protocol: Incoming raw sheet inspection (bubble, scratch, and inclusion checks) -> CNC dimensional verification -> Surface stress/tempering validation -> Cleanroom optical/surface finish inspection -> 100% final cosmetic and functional testing prior to packing.
* Test Documentation: Upon request, shipments include full CofC (Certificate of Conformance), Dimensional Inspection Reports, Spectrophotometer Transmission Curves (UV/VIS/IR), Water Contact Angle (AF) Reports, and ITO Sheet Resistance/Thermal Rise Logs. All materials are fully RoHS and REACH compliant.
