1.1.20. Focal Length, Resolution and Field of View
From the forgoing we see that neither resolution alone, nor field of view alone, are dependent
solely on the number of pixels of a sensor. So when are more pixels better? The key word in the
first sentence is “alone.” If all other factors are equal, more pixels will yield a larger field of view
compared to another camera with fewer pixels of the same size. The STL-6303 and the STL-11000
both have CCDs with 9 micron pixels. The resolution will be the same through any optical system.
However, the STL-11000 has more pixels and therefore at a given resolution it will have a larger
field of view. To see how these various factors are affected by varying the focal length of the
optical system, use the chart below. This chart shows both pixel field of view and the resulting
CCD field of view at given focal lengths for each of the Research Series cameras
