WebMay 2, 2012 · The result is a magnified, real image. This microscope lens (in reality an optical system consisting of several lenses) is called the objective. Then a second lens is used to pick up this image exactly in its front focal point. As a result we generate a beam of parallel rays, but not a real image. This optical element is called eyepiece. WebInfinity optical systems allow introduction of auxiliary components, such as differential interference contrast (DIC) prisms, polarizers, and epi-fluorescence illuminators, into the parallel optical path between the objective and the tube lens with only a minimal effect on focus and aberration corrections. Older finite, or fixed tube length ...

WebThe objective forms a case 1 image that is larger than the object. This first image is the object for the eyepiece. The eyepiece forms a case 2 final image that is magnified even further. Real lenses behave somewhat differently from how they are modeled using rays diagrams or the thin-lens equations. Real lenses produce aberrations.
