The advantages of a longer tube lens focal length becomes apparent when comparing systems having a focal length range between 160 and 250 millimeters. When the tutorial initializes, theFocal Lengthslider is set to a value of 200 millimeters and the objective exitPupil Diameterequals 17 millimeters....
