20 percent?

The reference #6 doesn't appear to mention the specific number of 20 molar percent in the statement for which it is used. Where does this come from? --SoledadKabocha (talk) 20:21, 2 December 2013 (UTC)[reply]

Anomalous partial dispersion?

The article cites the term "anomalous partial dispersion" without providing an operational definition for the term. The article states that the use of APD glass devices was pioneered by Leitz, without bothering to define what constitutes APD glass. As it stands the article is obfuscatory rather than clarifying. — Preceding unsigned comment added by 172.78.82.134 (talk) 17:04, 30 January 2017 (UTC)[reply]

References

I noticed a number of references using the url to a Google Book link. I though editors might be interested in a tool which takes a link as input and creates a (usually) properly formatted ref.

Wikipedia citation tool for Google Books

I used it to improve two such references.

It really helps creates a much cleaner list of references. I hope you will try it. S Philbrick (Talk) 23:20, 12 February 2016 (UTC)[reply]

Stub to Start and Addition to Photography Project

Article was moved from Stub to Start status in the Glass project because it has a significant amount of information and multiple references. In addition, the main article has not had a Stub tag for some time. Further, this article was added to the Photography project because of the numerous references to lens and lens manufacturing.
