What Happens to Our Vision with Negative Refraction in Lenses?

AI Thread Summary
Negative refraction in lenses alters the way light interacts with materials, leading to unique visual effects. When light passes through a medium with a negative refractive index, it can create unusual appearances of objects, potentially distorting their shapes and positions. Snell's law remains applicable, but the interaction at the interface between negative and positive indices results in unexpected outcomes. This phenomenon could impact the functionality of optical devices like lenses and binoculars, changing how we perceive images. Understanding these effects is crucial for advancements in photonics and optical technology.

The angles don't change in Snell's law if you replace all indices of refraction by negative numbers. Only where you have an interface between a negative and positive index medium do strange things happen.

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...
