WebBesides, its formula is: Magnification (m) = h / h’ Here, h is the height of the object and h’ is the height of the object. Besides, it can also be related to the object distance and image distance. So, it can be written as: m = -v / … WebThe formula for diffraction limited resolution is: where: λ (lambda) is the wavelength of light NA is the Numerical Aperture. In the previous example we considered a sensor with 4 micron pixels used with an objective with 40X magnification and a numerical aperture of 0.8. The sensor and magnification provide 100 nm geometric resolution. WebDistortion is a monochromatic optical aberration describing how the magnification in an image changes across the field of view (FOV) at a fixed working distance (WD); this is critically important in precision machine vision and gauging applications. Distortion is different from parallax, which is the change in magnification (FOV) with WD (more ... the ability to produce antibodies is called
