If you're using millimeters, multiply the aperture by 2. To change the resolution, a different lens is often the only answer. If an object was for example 0.1 mm in size, then it would appear as 20 mm in the magnified image. The objective and ocular lenses are responsible for magnifying the image of the specimen being viewed. Most compound microscopes have a 10x eyepiece and three objectives, 4x, 10x and 40x.

Try adjusting the ocular distance, check that the intensity of your light isnt too high or too low. To use an oil immersion lens, place a drop of oil on top of the dried specimen on the slide and carefully focus the microscope so that the objective lens is immersed in the oil. Often is at10X magnification, but can be different. What is the difference between magnification and total magnification? To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. The Optical System. If the viewer changes to the 10x objective lens, the total magnification will be the oculars 10x magnification multiplied by the new objective lenss 10x magnification, calculated as 10 10, for a total magnification of 100x. Watch this Video on how to use a Microscope, filmed at NC State Microbiology labs: https://www.microscopeworld.com/t-usrsion_oil.aspx, https://courses.lumenlearning.com/miof-microscopy/, status page at https://status.libretexts.org. Compound light microscopes are the name of such microscopes. The total magnification will depend on which objective lens you are usingthe highest magnification possible on these microscopes is typically 1000Xmeaning that objects appear 1000X larger than they actually are.

Microscopy is used by scientists and health care professionals for many purposes, including diagnosis of infectious diseases, identification ofmicroorganisms(microscopic organisms) in environmental samples (including food and water), and determination of the effect of pathogenic (disease-causing) microbes on human cells. Once the magnification of each individual lens is known, calculating total magnification is simple math. Note movements and draw the organism as you see it. This calculation is especially useful for operators to accurately ascertain the total magnification of a viewing instrument before the commencement of the inspection. Use the coarse knob to focus: the image may be small at this magnification, but you won't be able to find it on the higher powers without this first step. A microscope is an instrument that magnifies an object so that it may be seen by the observer. Rotating the nosepiece lets the viewer change the magnification.
