I did a bunch of websearching on "integrating spheres", so I think I have a few references to paste in within a day or so. jimswen 08:59, 26 November 2006 (UTC)[reply]

I'd like to thank those who added references and pictures. Maybe we can add some simple math relating to interior paint reflectivity and open-port percentage. -- jimswen (talk) 20:41, 29 January 2009 (UTC)[reply]

Those references are not reachable as of now in the end of 2011. 212.201.78.170 (talk) 15:01, 12 December 2011 (UTC)[reply]

Hello fellow Wikipedians,

I have just added archive links to one external link on Integrating sphere. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

• Added archive https://web.archive.org/20090815182409/http://www.sphereoptics.com:80/assets/sphere-optic-pdf/sphere-technical-guide.pdf to http://www.sphereoptics.com/assets/sphere-optic-pdf/sphere-technical-guide.pdf

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

In the first part of the figure, dealing with transmittance measurement, shouldn't the bottom port simply be plugged (i.e. covered with the same material as the rest of the inside of the sphere) rather than being fitted with a reflectance standard?
