Field of View FN Objective Magnification x Auxiliary Lens Magnification For instance if your eyepiece reads 10X22 and the magnification of your objective lens is 40. To simply put the working distance of a microscope is the distance between the subject and the lower part of your microscope. The working distance decreases as you increase magnification.

Working Distance WD The distance between the front edge of the objective lens and the specimen surface with the surface of the. Working distance refers to the space between the front lens element or tip of the microscope lens and the closest cover slip surface. Microscope objectives are generally designed with a short free working distance which is defined as the distance from the front lens element of the.

Max distance maintaining When referring to microscopes working distance is distance between the lens and the object being magnified. The working distance WD is determined by the linear measurement of the objective front lens to the focal plane. But Im still not sure how to even calculate the working distance of an objective with 2 lenses.

Microscope working distance is the amount of distance required between the objective lens and the top of the object in order for the sample. So if an instrument is 300 mm long you would not want the microscope at 200 mm. The working distance WD is determined by the linear measurement of the objective front lens to the focal plane.
