It is important to know that an image that hits the sensor through the optics, i.e. the lens, has a round shape. The sensor, however, is rectangular. Thus, the image circle should always be larger than the area of the sensor in order not to &#8220;give up&#8221; any sensor area and to avoid dark spots at the edges of the image.<br>\nDepending on the size and geometric format of the sensor and optics, the image circle can be very different. However, especially when selecting suitable lenses, this size serves as a guide. For optimal image quality, the image circle and sensor area should match well.<br>\n<\/span><\/p>\n<blockquote>\n<p>The sensor of the X71 camera used in our systems has an image circle of 43 mm. <\/p>\n<\/blockquote>\n<div class=\"row\"  id=\"row-1859475096\">\n\n\n\t<div id=\"col-1230445022\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\n\t<div id=\"gap-672107180\" class=\"gap-element clearfix\" style=\"display:block;
