Since it is a hot light, it is not recommended where heat is an issue, such as live specimens. The upper part of the microscope that contains the eyepiece tube and prisms. Invented by Fritz Zernike, they convert small phase shifts in the light passing through the specimen into changes in contrast. Describe the use of lens power and eyepiece powers. The objective lens magnifies the object "X" number of times to create the real image, which is then magnified by the ocular lens an additional 10X in the virtual image. accurately the entire contents in a microscope feld.
