viewed will change its size depending upon whether high- or low-power objective lenses are used. For example a cell viewed with the x40 objective will appear much larger than when viewed with the x10 objective. However because the graticule is in the eyepiece it will not change its size. Therefore the value of each of the divisions in the eyepiece graticule varies with the magnification of the objective lens. • A stage micrometer is a very accurately etched glass or plastic

cabinet. There are 3 main parts of the microscope such as illuminating parts‚ magnifying parts and mechanical parts. The sub-parts in illuminating parts are electric lamp and iris diaphragm while the sub-parts of magnifying parts are eyepiece and objective lens. The mechanical parts consist of most sub-parts among these three such as barrel‚ arm‚ stage‚ coarse focus knob‚ fine focus knob and base. Figure 1 : Fully Assembled Optical Microscope

resulting in an image that your naked eye would ordinarily see if looking at the slide. The image is then magnified by the lower (objective) lens. The objective lens flips the image and magnifies it by bending the light. The light is bent as it passes through the convex surface on either side of the lens material. The eyepiece acts as a weaker version of the objective lens by flipping the image again and magnifying it further. Compound microscopes are used most commonly
