Measure reflectivity of mirror polished stainless surface
What is the best way to measure reflectivity of a mirror polished stainless surface?
Does anybody know what is the reflectivity numbers for a regular glass mirror?

We use a Solar spectrum reflectometer, Manufactured by Devices and Services Co. Dallas, Texas.
Reflectivity of a regular glass mirror is R am2 = .882
Hope this helps,

Thanks Max.
Our interested customer performed their tests using:
Helium Neon Laser at 633 nanometer wavelength
Results: 63-64% reflectivity on Super #8 mirror polished stainless
and 56-57% reflectivity on Super #8 mirror polished stainless
with titanium nitride (gold color finishes).
I'm told these number is below regular glass mirrors...but very good for mirror polished stainless surface.

R&D division of Kombassan Holding is working on the development of a solar energy system.
We plan to commercialize the system within the next couple of years.
I want to measure mirror surface's reflection efficiency. I learned that reflectometers used on this subject, we want to buy one. We need a portable reflectometer. I want to get detailed technical information.
Is there a distributorship in Turkey? Could you send me catalogues, price list and brochures.
Thank you very much in advance for your help.

Hello! I have a question about the equation R am2 = .882. What do the variables represent (R, a, m). Also is that m^2? Thanks!
