To deliver zero-defect product, Inrad Optics operates under a comprehensive quality system that includes:
State-of-the-art Metrology. We employ a wide variety of metrology techniques to ensure that all optical properties and dimensions are within specification.
Strict Adherence to Technical Requirements. All customer specifications are carefully analyzed and clarified prior to commencement of production. Most of our production additionally complies with latest-revision DOD and ASTM specifications.
Tracking and Traceability. Our MRP system allows us to electronically track and document every product on its journey through the manufacturing life cycle–from initial order and design review to manufacturing, quality assurance and shipping. The system offers shop-floor access to detailed customer specifications along with relevant DOD and ASTM requirements.
