New ISO 14997 2011 Edition released on Test methods for surface imperfections of optical elements

ISO 14997:2011, titled “Optics and photonics — Test methods for surface imperfections of optical elements,” has just been released.  It is the second edition of the standard and replaces the first edition, ISO 14997:2003.

ISO 14997:2011 establishes the physical principles and practical means for the implementation of methods for measuring surface imperfections. This method evaluates the surface area obscured or affected by the imperfections.

ISO has released this new revision of ISO 14997 in order to adjust the standard to ISO 10110-7:2008 (“Optics and photonics – Preparation of drawings for optical elements and systems – Part 7: Surface imperfection tolerances”).
