WebStep 4: Building a Light Supply. A key difference in a fluorescence microscope is the light supply. Instead of white light (i.e. many wavelengths) that is used in brightfield microscopes, fluorescence microscopes require light of a specific color (i.e. a narrow range of wavelengths). For example, blue light has a wavelength around 488nm. WebThe total magnification is the product of the ocular magnification times the objective magnification: ocular magnification × objective magnification. For example, if a 40⨯ objective lens is selected and the ocular lens is 10⨯, the total magnification would be. ( 40 ×) ( 10 ×) = 400 ×. Figure 2.12 Components of a typical brightfield ...
