Gently set a coverslip over the smear and scan your slide under low power to locate the cells, then observe them more closely under high power. The second method of preparing specimens for light microscopy is fixation. 5. Ek=+2cosNC2kkk=0,1,2,,NC/2(evenN)=0,1,2,,(NC1)/2(oddN). They work by using two lenses: an objective lens close to the specimen being viewed and an ocular lens or eyepiece. To. Images observed under the light microscope are reversed and inverted.
