An example of a focal point is a bright red … WebAn iris or aperture is placed at the focal point of the objective. This determines how bright the object will appear. The wider the iris, the more light gets through it, and the brighter the object appears. Draw a thin lens to represent the objective and draw an iris at the focal point to the right of the lens. WebThe best means of summarizing this relationship is to divide the possible object locations into five general areas or points: Case 1: the object is located beyond the 2F point C ase 2: the object is located at the 2F point Case 3: the object is located between the 2F point and the focal point (F) Case 4: the object is located at the focal point (F) csvmapper header
