Meiji Techno Halogen Ergonomic Trinocular Brightfield,Phase Contrast Biological MT4310EH

Hi, I’m Ted Salmon, and I want to provide, today, an introduction to four modes of transmitted light microscopy that give contrast to transparent specimens which are very important in cell biology and other biomedical fields, particularly for live cell imaging, and these are darkfield, phase contrast, polarization, and differential interference contrast, which is also called DIC microscopy. Now, microscopes are designed with three essential functions. One is the magnification, and that is… to make structural detail visible to the detector, which is the eye or the camera, we need sufficient magnification not to be limited by the resolution of the detectors. The second is microscopes are designed to provide resolution that is only limited by the wavelength of light and not by lens… optical aberrations, and these are mostly taken care of by the manufacturer of microscopes. And the third is
