Detailed explanation-1: -Most educational-quality microscopes have a 10x (10-power magnification) eyepiece and three objectives of 4x, 10x and 40x to provide magnification levels of 40x, 100x and 400x. Magnification of 400x is the minimum needed for studying cells and cell structure.
Detailed explanation-2: -Use coarse focus knob to raise the stage until the 100x lens just touches the oil. 7. While looking into the microscope, use fine focus knob (turn clockwise, to raise the stage) to find the plane of focus where the specimen is.
Detailed explanation-3: -Compound Microscopes Typically, a compound microscope is used for viewing samples at high magnification (40-1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).
