Objective field number

Field Number (F.N.) and Field of View (F.O.V.). The field number (F.N.) is referred to as the diaphragm size of eyepiece in mm. UISObjective Lens Lineup. The field size in the specimen plane is then defined as the field number divided by the.

If an auxiliary lens is inserted between the objective and eyepiece, the . The field diameter in the object (specimen) plane becomes the field number divided by the magnification of the objective.

Although the field number is often limited by the magnification and diameter of the ocular (eyepiece) field diaphragm, there is clearly a limit that is also imposed by the design of the objective. Aug Field number is the diameter of the eyepiece lens and is most often expressed in millimeters. It is the circular area that is seen when looking through the microscope.
