Laboratory work, magnification

  1. Oct 24, 2012 #1
    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?
