Can someone please point me to an academically verified web resource/page that tabulates the Reflectivity of various metallic surfaces like gold, silver , aluminum, etc.? I have found a list on Engineering Toolbox but I am not sure of its credibility. I would prefer an academic resource to cite in my work.

Thank You

  • $\begingroup$ Reflectivity depends very much on surface conditioning and there are no easy answers here. Try reading photonics.com/EDU/Handbook.aspx?AID=25501 for starters, it will give you a little more detail what's going on for technical purposes. The detailed theory is a lot deeper, still... $\endgroup$

  • $\begingroup$ Thanks for the link..yes I understand that it is both a function of surface roughness and the material property $\endgroup$ Commented Jun 27, 2016 at 13:15

From refractiveindex.info you can get n and k for many different materials, as a function of wavelength, and the site even includes a calculator at the bottom with which you can calculate the reflectivity R.

All of the provided data are backed up with citations.

  • $\begingroup$ @BenCrowell The site lists n&k values for many materials over broad ranges of wavelength with scientific reference. Definitely not a black box and precisely the answer requested. $\endgroup$
