Field of view equation telescope
WebThe problem is overcome by placing a field lens at the intermediate focus between the objective and eye lens. This will produce a wider field of view, and the field will be uniformly illuminated. This is shown in Fig. 4.7. The field lens is at the image plane so the power of the telescope is unchanged. However, any dust or scratches on the WebThis is known as the angular field of view (AFOV) and is required to determine the overall FOV. The AFOV is the angle between any light captured at the horizonal, and any light captured at the edge (as shown in Figure 2). If you have a fixed sensor size, altering the focal length will alter the AFOV and therefore the overall FOV.
