About the Website

Inspection of Optical elements (items) is important issue for approving their conformance to requirements in manufacturing, starting in design, continues in production and ends in delivering to the customer (inner or outer). There are many subjects dealing with inspection of optical elements and they are spread widely in standards, specifications, manufacturers' procedures and additional articles/report in internet Websites. Some of subjects are clear to all, others are complicated, and sometimes misunderstood or not acceptable by the users. 


In this website, I gather some important articles/reports from selected subjects, approved for use in my Website by their owners, so the intended user, mostly optics inspector and even optics designer can read and find the needed material. 

This is not a commercial website, meaning that even some articles/reports refers to some tool and its manufacturer, I do not recommend for any mentioned tool. It is the obligation of the intended user to buy the correct tool for his matter. I also do not recommend to use any of the procedures mentioned in the Website. It is also the obligation of the intended user to choose the best for him.

Everything in the Website is with permissions. If I made some mistake by putting some Website link of article/report without a permission and you see it, let me know about. If some reader or organization would like to add his article/report relevant to the subject in this Website, send it to me and I will be glad to do it.

This is also a place to thank all organizations and people that gave me the permission to put their material in this Website. Thank you!
