Laboratory work, magnification

AI Thread Summary
To determine the magnification of an interference pattern projected onto a CCD, one must consider the specifications of both the lens and the CCD. The lens magnification factor, such as 10x, does not directly translate to the final image size without accounting for the lens's numerical aperture (NA) and focal length. The CCD's resolution, which is 2448x2050 pixels with a pixel size of 3.45 µm, also plays a crucial role in calculating the effective magnification. Detailed knowledge of optics is essential to accurately assess how the interference pattern will be captured by the CCD. Understanding these parameters is vital for achieving the desired magnification in laboratory work.

I am working with interference which pattern I want to magnify to a CCD. The question is how can I determine the magnification of the interference pattern to the CCD? An aperture lens is used. I know the CCD cell size.

It is not enough to say that the lens is 100x .. then the magnification is 100?

Can you give us some details on your lens and CCD?
What is the diameter of the aperture lens, the focal length, etc.
How big is your CCD? How many pixels? How big are the pixels?

CCD have 2448x2050 and pixel size is 3.45um.
A lens that can be used is for example 10x, NA = 0.3.
 
You can't just shine the pattern into the camera lens and expect to get a magnified image.

Do you have a knowledge of optics?

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...
