ISO 8980-4:2006 specifies optical and non optical requirements, including durability, and test methods for anti-reflective coatings on spectacle lenses. ISO 8980-4:2006 does not deal with the following topics: transmittance and absorbtance; the colour of the reflected light.
Abstract
Overview
ISO 8980-4:2006 - Ophthalmic optics - Uncut finished spectacle lenses - Part 4: Specifications and test methods for anti-reflective coatings defines optical and non‑optical requirements and standardized test methods for anti-reflective (AR) coatings on spectacle lenses. It sets measurable criteria for reflectance and durability and specifies how to measure spectral, luminous and mean reflectance for uncut finished lenses. The standard explicitly excludes transmittance/absorptance and the colour of reflected light.
Key topics and technical requirements
- Reflectance measurement
- Spectral range: 380–780 nm; wavelength step ≤ 5 nm; spectral bandwidth (FWHM) ≤ 5 nm.
- Instrument: dual‑ or single‑beam spectrophotometer with incident angle ≤ 17° and measurement uncertainty
