polycarbonate NIR spectrum - sample thickness?
Deglr6328,

This is my first attempt to do something other than browse/view Wikipedia content, so please be kind. I have a comment regarding the NIR absorbance spectrum for polycarbonate, and this comment may apply to other spectra you have contributed. In the polycarbonate spectrum, the vertical axis is % transmission, but no pathlength/material thickness figure is given. Hence, this is really a relative absorbance spectrum. If the path length is available, it would be really useful if it were indiccated on the spectrum.

Thanks for your contribution, which has been helpful to me already.

Cheers, eqpi


 * Cool I'm so glad the information was of use to you! I used a pair of plastic saftey goggles from UVEX to get that transmittance spectrum. Here they are . Unfortunately they dont provide any information on the thickness of the lenses. Tell you what, tomorrow I will measure them and let you know here. --Deglr6328 05:04, 14 February 2007 (UTC)


 * The path length of the polycarbonate was 2.3 mm. Hope that helps! --Deglr6328 21:35, 14 February 2007 (UTC)
