AI Thread Summary

The position of an image formed by a lens or mirror when the object is not on the principal axis can be determined using linear magnification. This method involves calculating the image location based on the object's distance from the optical axis and the lens or mirror's properties. The discussion emphasizes that off-axis objects can still produce images, but their positions will differ from those of on-axis objects. Understanding this concept is crucial for accurate optical design and analysis. The principles of geometrical optics remain applicable even when the principal axis is not involved.

What would be the position an image formed by a Lens or a mirror if the object is not kept on the principal axis?

We often use the linear magnification to calculate the location of an image of an off-axis object.

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...
