Dec 27, 2018 · Linear magnification is calculated from the physical size of object and image, as measured by a ruler or similar linear measuring device. This is usually used with optical systems which provide a real image. Magnification is simply the size of the image divided by the size of the object that was magnified. *In the equation for working f/#, m represents the paraxial magnification (ratio of image to object height) of the objective. Note that as m approaches zero (as the object approaches infinity), the working f/# is equal to the infinite f/#. It is especially important to keep working f/# in mind at smaller working distances. Infinity-Corrected Microscope Conjugate Field Planes.

Object distance, image distance, and magnification. Throughout this article we use the word "object" to mean the thing of which an image is being made. It is loosely equivalent to the word "subject" as used by photographers. In lens formulas it is convenient to measure distances from a set of points called "principal points". Since a decent imaging system where this is not the case for all rays must still focus the paraxial rays correctly, this matrix method will properly describe the positions of focal planes and magnifications, however aberrations still need to be evaluated using full ray-tracing techniques. Optics, science concerned with the genesis and propagation of light and with the changes that it undergoes and produces. Physical optics deals with the nature of light itself. Geometrical optics has to do with the principles that govern the image-forming properties of devices that make use of light.
