How to calculate the total magnification of a microscope. M hp is the higher power objective lens magnification and. How to calculate total magnification basic microscope design. For example for a microscope with a 10 eyepiece and 45 objective the magnification is 10 45 450 and the field of view is 033 mm.
If the eyepiece magnification of a microscope is 10x and the objective lens in use has a magnification of 4x calculate the magnification of the microscope. Magnifying objects focusing image. M lp is the lower power objective lens magnification.
When viewing a slide through the microscope make sure that the stage is all the way down and the 4x scanning objective is locked into place. 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. The formula for calculating microscope on screen magnification is.
Stereo microscope magnification is a combination of the eyepiece magnification most commonly 10x and the objective lens magnification typically anywhere between 07x 5x. Total magnification optical magnification x digital magnification. Equal to the power of the ocular lens multiplied by the power of the objective lens being used magnifies 45x total magnification is 450x 10 x 45.
If the magnification power of the ocular lens is 10x and that of the objective lens is 4x total magnification is 40x. Microscopes use lenses to magnify objects. If you are using a stereo microscope with 10x eyepieces and the zoom knob is set to 4x the total magnification formula would look like this.
If your microscope only uses an eyepiece this is all you need to do but if your microscope uses both an eyepiece and an objective lens multiply the eyepiece magnification by the objective magnification to find the total magnification before dividing the field number. This one is fairly simple. The total magnification of 40 means that the object appears forty times larger than the actual object.
Optical magnification objective magnification x c mount adapter magnification. How is optical magnification calculated. 10 x 4 40x magnification.
