SIMPLE MICROSCOPE A Simple microscope is commonly used in a laboratory. It is most usually used for dissection of small organisms or for getting the magnifying look at certain organs of organisms e.g. while studying mouthparts or insects. In a simple microscope single or group of convex lenses is used. A convex lens magnifies the object and helps to produce a magnified image. Magnification obtained by simple microscope can be calculated as Where D = the least distance of distinct vision F = Focal Length of convex length This microscope can provide magnification only up to 3 times. In cases where greater magnification is required, more than one lens should be used. A Simple microscope consists of two parts viz. A. Optical Part B. Mechanical Part A. Optical Part : It consists of a single convex lens B. Mechanical Part : As the name suggests it provides the mechanical support to the microscope. It holds the lens at the proper posi
