Laboratory work, magnification

[nordmoon]

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?

I would first recommend conducting a calibration study to accurately determine the magnification of the lens being used. This could involve using a known standard with a known size and measuring the resulting image on the CCD. Once the magnification of the lens is determined, you can then use the CCD cell size to calculate the overall magnification of the interference pattern to the CCD. This will ensure the accuracy and precision of your measurements. Additionally, it may be helpful to consult with colleagues or reference materials to determine the appropriate equations and techniques for calculating magnification in your specific experimental setup.
