شهادة معايرة قياسية 33 مم، ملحقات 4 بوصة و6 بوصة

Had a local machine shop check my 33mm standard against the new cert file, and the wavefront error matched within a few nanometers. Exactly what I needed for my interferometer setup.

The USB drive with the system error file was a nice touch—made plugging the data straight into our interferometer workflow painless. Turnaround was quicker than quoted, and the cert covers both the 33mm standard and the 4" and 6" accessories in one tidy package.

The certification paperwork arrived promptly and included detailed traceability data for each standard size. I appreciated that the system error file was pre-loaded on the USB drive, making setup straightforward. Everything I needed for my 33mm, 4", and 6" accessories was covered in one service.
