600nm is approximately orange, not infrared. This article needs correction.

Those who can read are clearly at an advantage here:

It is transparent for infrared light wavelengths over 600 nm.

Those who actually DO read apparently have an even greater advantage. The problem still remains with the article. It currently states: . ....low absorption of infrared wavelengths up to 600 nm,.... . Infrared doesn't begin till at least 750nm. There are no infrared wavelengths 'up to 600 nm'. . The statement is as silly as saying something like 'all parts of Antarctica as far south as the equator'. . 70.171.44.124 ( talk) 15:49, 9 October 2013 (UTC)BGriffin reply
