To ensure that it was using the best equipment for the task, a company that develops innovative virtual reality (VR) solutions turned to Zygo, the leading optical metrology innovator.

When companies need to scale up the size of their windows and mirrors while maintaining the most exacting of optical specifications, the competence of a chosen partner is essential.

Join the optics and photonics community in this exploration of the latest breakthroughs and cutting-edge research.

As manufacturers continue to produce a growing number of different optics of varying size and shape, they need a flexible metrology system that can measure multiple parts without major re-tooling.

Non-contact metrology can help overcome the quality assurance challenges that come with producing consumer electronics devices featuring a wide variety of materials and design complexity.

Freeform optical surface shapes have evolved from an intriguing optical design concept to a practical necessity for applications ranging from space and defense to consumer electronics. The demand is no more strongly felt than in the development of digital immersive displays for AR/MR. 

Government regulations and health and safety standards guide the development process for optical medical devices from beginning to end. Unlike other industries where engineers can correct an optical design misstep after the prototype phase, governmental compliance, schedules, and budgets leave little room for changes or improvements after product introduction. Learn some of the key measuring mistakes to avoid ahead of time. 

Fuel cells have recently penetrated the electric vehicle market due to their efficiency, quick refueling, and longevity. Many of today’s larger truck manufacturers are looking to fuel cells as a long-haul goods transport solution that can also reduce harmful emissions.

Did Denis Gabor build the first all-optical computer for processing interference fringe patterns? Was Isaac Newton the first to create a synthetic off-axis hologram? Is my white-light 3D profiler actually a digital holography system? These are some of the questions addressed in this paper, which considers the many contributions of holography to the advancement of interferometry for surface topography measurement.

In this case study, Zygo Advanced Imaging Group's TINT Virtual Stepper Defect Analysis System's ability to predict CD printability of various known features on photomasks is tested. The validation of this tool will help keep both mask makers and wafer makers on schedule.

In this episode of “Metrology Matters,” two experts in the field, Bruce Truax, director of engineering at Zygo, and Kate Medicus, CEO of Ruda Cardinal, introduce us to laser interferometry. They provide an overview of laser interferometry, its importantance in producing small optics, its applications in the industry, and its best practices.

This webinar discusses the vibration effects on a measurement using Phase Shifting Interferometry (PSI), solutions for mitigating the vibration effects, and dynamic alignment techniques for use in challenging environments.

This webinar will discuss the precise measurements of super-smooth polished surfaces and present a case study with real-world examples on these types of samples.

This webinar by ZYGO discusses the use of Mx™ data with optical design software for optical modeling and measurements.

This webinar presentation discusses the Part Finder & SmartSetup features, the Level/Step tool, and customized workspace available with ZYGO 3D optical profilers.
