What is the object distance for a concave mirror?

AI Thread Summary
The object distance for a concave mirror is measured from the object to the vertex of the mirror, which is the center of the concave surface. This distance is crucial for calculations involving image formation and mirror equations. Understanding this measurement helps in accurately determining the properties of the image produced by the mirror. Properly identifying the object distance is essential for effective use of concave mirrors in various applications. Accurate measurements ensure correct predictions of image characteristics.

Hey eveyone,

I have a concave mirror and an object x distance away from the mirror. I am wondering if anyone knows where you measure from in order to determine how far away the object is from the mirror. Is it from the object to the center of the concave mirror?

Thanks,

Yes, the "object distance" is the distance along the mirror axis from the object to the vertex of the mirror (the center of the concave surface).

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...
