معيار خطوة 1.75 ميكرومتر مع شهادة ZYGO

Went straight into our interferometer and the step height landed exactly where it should, no surprises. The ISO 17025 paperwork in the box gave me real confidence for our calibration audit.

The step height on this standard measured out exactly as specified when I ran it on our interferometer, right down to the nanometer. The included ZYGO certification gives me full confidence in the traceability for our calibration audits.

The ZYGO certification paperwork that came with this step was exactly what our auditor wanted to see, no back-and-forth needed. The 1.75um step itself reads clean and consistent every time we check it against our interferometer.
