This exclusive service provides an economical way to measure and/or certify your samples with ZYGO's precision, non-contact, surface and optical measuring instruments!

When you need the accuracy and NIST-traceability of ZYGO precision surface and optical measuring instruments, but you don't have the volume to justify a purchase, ZYGO's Testing & Certification Services is an excellent, cost-effective solution!

Our facility is one of the most complete and modern in the industry.
We have state-of-the-art equipment for testing:

• Microroughness of precision surfaces
• Air bearing surface geometry of magnetic heads
• Optical components and systems: Flats, Spheres, Parabolas, Prisms
• Surface Angles
• Reflective and antireflective coatings
• Specular surfaces of all kinds

Our engineers and technicians stay abreast of the latest developments in precision measurement and testing, often pioneering advanced testing techniques themselves.

We also offer absolute calibration of spheres and flats, as well as large aperture plano surfaces.

To assist you in establishing and maintaining a routine calibration program, we can automatically notify you when the next certification is due.
