Overview
ISO 10110-17:2004 - "Optics and photonics - Preparation of drawings for optical elements and systems - Part 17: Laser irradiation damage threshold" defines how to indicate laser‑induced damage thresholds on technical drawings for optical components. It standardizes the presentation of damage limits (as defined in ISO 11254-1) so manufacturers, coating engineers and inspection teams can unambiguously record the maximum laser exposure an optical surface shall withstand without damage.
Key topics and requirements
- Scope: Applies to finished optical surfaces, including surface treatments and coatings.
- Damage definitions: Uses the laser‑damage concepts from ISO 11254‑1/2 (1-on-1 and S-on-1 test methods).
- Parameters required on drawings:
- For pulsed lasers: damage threshold expressed as energy density H (J·cm⁻²) or power density E (W·cm⁻²) plus wavelength (λ) and effective pulse duration (τ_eff).
- For long‑pulse and continuous wave (cw) lasers: threshold as linear power density F (W·cm⁻¹) with λ and τ_eff (or irradiation time for cw).
- Units for H, E, F, λ and τ must be explicitly stated.
- Indication format: Uses code number 6 on ISO 10110 drawings. Examples:
- Pulsed:
6/H; λ; τ_eff or 6/E; λ; τ_eff
- Long‑pulse/cw:
6/F; λ; τ_eff (or irradiation time for cw)
- Example from the standard:
6/25 J·cm⁻²; 1064 nm; 20 ns
- Additional test parameters: State/plane of polarization and angle of incidence should be specified where relevant and tests must follow ISO 11254 series.
- Placement: Indication is linked by leader line to the specific surface and can be grouped in tables per ISO 10110‑10. Associated surface codes (e.g., 3/, 4/, 5/) may be used.
Applications and users
ISO 10110‑17 is practical for:
- Optical designers and systems engineers specifying laser‑compatible components.
- Coating manufacturers documenting laser‑damage requirements for thin films.
- Component manufacturers and quality control/inspection teams verifying compliance during production.
- Procurement/specification writers and system integrators who need clear, unambiguous drawing notes for laser‑safe optics.
Typical use cases include lenses, mirrors, windows and other optical elements used in high‑power lasers, medical lasers, industrial processing, research lasers, and defense applications.
