Place the slide that you want to view over the aperture and gently move the stage clips over top of the slide to hold it into place. = numerical aperture, from which the limit of resolution can be calculated: limit of resolution = wavelength. Magnification is measured by multiples, such as 2X, 4X, and 10X, indicating that the object is enlarged to twice as big, four times as big, or 10 times as big, respectively. This requires more sophisticated handling with immersion oil. Once the magnification of each individual lens is known, calculating total magnification is simple math. Magnification Limits What is the focal length of a plane mirror? 1. Magnification is a function of the image size and the object size. The ratio of image size to the object size determines the objects level of enlargement or magnification. 3. are off the benchtop. In the science of optics, the magnification of an object like a lens is the ratio of the height of the image you can see to the height of the actual object being magnified. Hence, the total magnification, in this case, is 100 times the original size of the object. In other words, OCC X OBJ = TM where Occ is the ocular lens magnification, OBJ is the objective lens magnification, and TM is the total magnification. 2. Different lenses and microscopes are often utilized to carry out total magnification for other purposes beyond X-ray imaging.
