EN ISO 24013:2023 PDF

Overview

EN ISO 24013:2023 (ISO 24013:2023) - Optics and photonics - Lasers and laser-related equipment - Measurement of phase retardation of optical components for polarized laser radiation - specifies standardized test methods to determine the linear optical phase retardation introduced by optical components when illuminated with polarized laser beams. This European adoption (CEN) supersedes EN ISO 24013:2006 and updates procedures, alignment tolerances and evaluation methods for modern laser metrology.

Key Topics

• Scope and purpose: Defines measurement methods for relative phase retardation with respect to X/Y (or s/p) polarization axes for transmissive and reflective optics.
• Measurement principle: Irradiation of the component with a defined polarized laser beam and analysis of the output polarization state to quantify phase retardation.
• Test arrangement and preparation:
  • Laser beam preparation (beam quality, polarization state).
  • Sample alignment and system calibration for reflective and transmissive samples (including a horizontal optical axis step for transmissive optics).
  • Detection system requirements: polarization analyser and power detector.
• Test procedures: Specific procedures for measuring phase retardances around 0, π/2, and values near π, with separate workflows when absorptance differences between polarization directions are zero or non‑zero.
• Evaluation and reporting:
  • Methods to compute phase retardation and handle absorptance differences.
  • Required content for the test report and reference to theoretical background (informative annex).
• Referenced normative documents: ISO 11145 (vocabulary & symbols), ISO 12005 (laser polarization test methods), and practical references to ISO 14644‑1 for cleanroom context where applicable.

Applications

Who uses EN ISO 24013:2023 and why:

• Optics manufacturers - to characterize and certify phase retarders, waveplates, substrates, coatings and elements used in polarization‑sensitive systems.
• Suppliers and procurement teams - to specify measurement acceptance criteria for delivered optical components.
• Laser system integrators and OEMs - to ensure polarization fidelity in systems for communications, lidar, microscopy, and precision metrology.
• Test laboratories and calibration facilities - to perform repeatable, traceable phase retardation measurements and issue standardized reports.
• Quality and R&D engineers - to validate production processes, coating effects and alignment sensitivities that affect polarized laser radiation.
