ISO 10110 consists of a series of standards numbered ISO 10110-1 through 10110-12 (dated 1996 or 1997) dealing with Optics and Optical Instruments; 10110-14 is in draft standard form. You might try a professional society or someone in a professional society related to optics. However, if anyone else has paid $102 for the series for their use, I find it hard to believe that they would willing share a copy as it could well result in copyright violations. And it could be owned by one of your competitors bidding on the same job.
