Sun ray brightness quality after mirror reflection

AI Thread Summary
Sun ray brightness quality after mirror reflection is influenced by the type of mirror and its materials, such as aluminum, silver, or tin. Normal vanity mirrors typically have a 90% reflectivity due to their aluminum second surface. The transparency and finish of the glass also play significant roles in determining mirror quality. To accurately assess the reflectivity of an unknown mirror, a photometer is required to measure the light intensity before and after reflection. Understanding these factors is essential for optimizing efficiency in light reflection.

What is the Sun ray brightness quality after mirror reflection and what affects it? How to get the efficiency after reflection?

It depends on the mirror
Normal vanity type mirrors are aluminum second surface at 90% reflectivity
The transparency of glass first or second surface silver aluminum tin nickel the finish of the surface
All are variables in mirror quality
If you want to measure the quality of an unknown mirror you need a photometer
Then you can measure and calculate the difference between source and reflection.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
