Optics and optical instruments — Test lenses for calibration of focimeters — Part 2: Test lenses for focimeters used for measuring contact lenses

Optique et instruments optiques — Verres étalons pour l'étalonnage des frontofocomètres — Partie 2: Verres étalons pour frontofocomètres pour le mesurage des lentilles de contact

Abstract / scope

ISO 9342-2:2005 specifies requirements for test lenses for focimeters that are used to measure contact lenses. These test lenses are used to find the precise correction values that are needed to convert the power values measured to back vertex power values.

ISO 9342-2:2005 applies to focimeters meeting the requirements of ISO 8598.
