For a 40X objective and 10X ocular Total magnification = 10 X 40 = 400X. To convert the measurements from . The objective lens gathers light from the specimen, which is focused to produce the real image that is seen on the ocular lens. The lens will be extremely close to the specimen! Total magnification, `m = m_1 xx m_2 xx m_3` . Take breaks if needed. Magnification involves the enlargement of an object many times bigger than its original size. d -image reversal What is the total magnification when using 100X? If your answer is between 0 and 1, the image is smaller than the object. Microscope: Microscopes are used to view and study microorganisms. 9.

The eyepiece, located closest to the eye or sensor, projects and magnifies this real image and yields a virtual image of the object. Return To Top of Page 2. Objects that are smaller than this cannot be seen clearly without magnification. If an object is viewed with the eye from a distance of 250 mm, the magnification is 1x. Magnification is defined as the ratio between the actual size of an object and the apparent size of the same object when seen through the microscope. The total magnification can be as low as 40 but reaches up to 1000, with exceptional magnification offered by certain solutions. 1.
