Reactive light microscopy
WebA compound microscope is defined as the type of microscope that has more than one lens. It has a combination of lenses and two optical parts known as an objective lens and an eyepiece or ocular lens. The magnifying power of the compound microscope is given as: m = D f o × L f e Where, D is the least distance of distinct vision WebFigure 23.52 Functions of fluorescence microscope filter set components. The desired excitation wavelength (λ 2) is selected from the spectral output of the lamp by the excitation filter (EX) and directed to the sample via the dichroic beamsplitter (DB).The beamsplitter separates emitted fluorescence (- - -) from scattered excitation light (—). The emission …
