ZYGO CORPORATION

Zygo Corporation specializes in the design, manufacturing, and integration of high-precision optical measurement systems and industrial instrumentation, with deep expertise in interferometry, optical profilometry, and metrology-grade sensor systems. Their core capabilities center on developing closed-loop control instruments for nanometer-level surface characterization, enabling critical quality assurance in semiconductor fabrication, aerospace components, and precision optical assemblies. The company’s technical differentiation lies in its proprietary interferometric platforms, such as the Verifire interferometer, which deliver sub-nanometer accuracy for industrial process monitoring and defect detection. Zygo’s solutions are engineered for demanding environments where repeatability, thermal stability, and real-time feedback are essential, making them indispensable in advanced manufacturing and R&D workflows requiring traceable metrology. The company maintains a strong relationship with the Department of Defense, delivering optical profiling and measurement systems used in defense-grade component validation and manufacturing process control. Their work with NASA supports precision instrumentation for space-based optical systems and test stand calibration, emphasizing reliability under extreme conditions. These agencies consistently engage Zygo for mission-critical metrology tools that demand compliance with stringent environmental and performance standards. Zygo operates primarily within NAICS 333310, 333314, and 334513, focusing on commercial and industrial machinery for optical measurement, lens systems, and process control instrumentation. Their market positioning is as a niche supplier of high-end metrology equipment for defense, aerospace, and semiconductor manufacturing verticals, where accuracy and system integration are non-negotiable. Zygo Corporation is a small business entity headquartered in Middlefield, Connecticut, with no federal certifications on record. Its geographic presence is concentrated in the Northeast U.S., serving government and industrial clients through direct engineering support and custom instrument deployment.
