Full title and description

Optics and photonics — Interferometric measurement of optical elements and optical systems — Part 2: Measurement and evaluation techniques. This Technical Report provides explanations of interferometric measurement objects, describes hardware aspects of interferometers and evaluation methods, and gives recommendations for test reports and calibration certificates.

Abstract

This Technical Report (ISO/TR 14999-2:2019, 2nd edition) gives fundamental explanations of interferometric measurement objects, details on interferometer hardware and configurations, evaluation and analysis techniques for wavefront and surface-form measurements, and recommendations for preparing test reports and calibration certificates for optical components and systems. It acts as guidance to support accurate, repeatable interferometric metrology in optics and photonics.

Scope

ISO/TR 14999-2:2019 provides guidance and explanatory material for interferometric measurement of optical wavefronts and surface form of optical elements and systems. It covers measurement objects, hardware aspects of interferometers, measurement and evaluation techniques, and recommendations for reporting and calibration documentation to support traceable optical metrology. The Report is intended to complement normative standards (for example ISO 10110 drawing conventions and related parts of the 14999 series) by describing practical measurement and evaluation approaches.

Key topics and requirements

• Fundamental description of interferometric measurement objects (wavefronts, surface form, reference surfaces).
• Hardware aspects and common interferometer configurations (including practical considerations for setup and alignment).
• Evaluation methods for converting interferometric data into metrics (phase extraction, filtering, form removal, Zernike/other decomposition).
• Error sources and uncertainty considerations relevant to interferometric measurements.
• Recommendations for test reports and calibration certificates, including content and presentation to support traceability and comparability.
• Guidance to complement ISO drawing and tolerance standards for optical components and systems.

These topics and recommended practices are described in the Technical Report to help laboratories and manufacturers achieve consistent interferometric measurement and reporting.

Typical use and users

Used by optical metrology laboratories, calibration and testing facilities, optical component and system manufacturers, research institutions, and quality/inspection teams. Typical activities include wavefront and surface-form testing of lenses, mirrors, and optical assemblies, development of measurement procedures, evaluation of instrument performance, and preparation of calibration/test reports consistent with traceability practices.
