(Middlefield, CT, USA 5^th August 2024) Zygo, a business unit of AMETEK, Inc. (NYSE: AME), is excited to be exhibiting at the SPIE Optics & Photonics 2024 event in San Diego, CA from August 20-22. At booth 317, members of the Zygo team will be available to discuss the company's leadership role in the area of 3D optical metrology innovation, and will be showcasing the QualifireTM laser interferometer, the NexView NX2 optical profiler, and also a 6 inch diameter Zygo made optical device.

3D optical metrology is crucial in advanced manufacturing for ensuring precision and quality control by providing accurate, non-contact measurements of complex geometries and surfaces. It enhances efficiency and consistency in production processes, leading to higher-quality products and reduced waste. Zygo is a key player in the area due to its patented cutting-edge interferometric technology and comprehensive solutions for high-precision surface and dimensional measurements. The company's innovative instruments and software provide unmatched accuracy and reliability, making them essential for quality control in advanced manufacturing industries.

Erin McDonnell, Product Manager Interferometers at Zygo says, "On show at the Optics & Photonics 2024 will be our QualifireTM laser interferometer which has been developed with user experience and confidence in metrology front and center. The Qualifire's Fizeau design uses a fixed, on-axis coherent point source to illuminate the interferometric cavity, the gold standard in optical metrology measurements. It is more portable than many of Zygo's other laser interferometers weighing in at less than 50 pounds (23kg), especially helpful when the test part cannot be brought to the instrument."

Another weight and spacing advantage is an internal Phase Measuring Receptacle (PMR), which eliminates potential damage to the piezoelectric transducer (PZT) stacks inside the PMR when the unit is moved. Other improvements include easy-grasp handles and a convenient, easy-to-access on/off switch. In addition, the optical leg is sealed, providing additional protection from dust that accumulates over time and can add to artifacts in the system. This layout also makes service easier. Even the laser can be changed without disturbing any of the optical components.

Also on show will be the NexView NX2 optical profiler. Zygo's optical profilers stand out in the market due to their exceptional accuracy, precision, and versatility, capable of measuring features down to sub-nanometer levels. This precision ensures that even the smallest surface variations are accurately captured, providing invaluable data for quality control and process optimization.

Michael Schmidt, Senior Product Development Manager at Zygo says, "The Nexview™ NX2 optical profiler is one of Zygo's flagship products and exemplifies the company's commitment to delivering high-performance metrology solutions. The Nexview™ NX2 offers fast, precise measurements of surface roughness, topography, and film thickness without the need for sample preparation and is designed to handle a broad range of surfaces, from super-polished optical surfaces with sub-Angstrom roughness to steep machined angles up to 85 degrees. The NX2, representing the benchmark for Zygo's optical profiling technologies, is designed to tackle the most challenging metrology tasks with precision and efficiency.

At Optics & Photonics 2024, the Nexview™ NX2 will be fitted with a uniquely designed and patented Zygo 0.5x objective. This objective is used to capture larger fields of view, beneficial for inspecting and measuring larger areas or components in faster time compared to higher magnification lenses. It is ideal for applications requiring quick scans of large surfaces or overall shape measurements, such as quality control of large mechanical parts such tool plates for mould pins, or optical components, like stacked optical assemblies for AR goggles.

Attendees at Optics & Photonics 2024 are invited to come to booth #317 to see the company's 3D optical metrology tools in action, and to discuss specific application requirements with the company's expert team.
