WebQ1: What appears to be the effect of using eyepieces with different focal lengths? Specifically, what happens to the magnification and the field of view as the focal length of the eyepiece is increased (pay careful attention to the direction of increasing focal length)? It appears that the shorter the focal length of the eyepiece, the closer an object … WebThus, magnification is 0.3 100 = 0.003 m m. Magnification can also be viewed as m = f u − f, so 0.003 = f 100 m m − f, which will give us f = 0.299 m m. From here, I know that it's possible to calculate the field of view, but how can I do it? I imagine the equation will use the image sensor size and the focal length. Thanks! optics vision imaging
