BoliOptics Polarizing Microscope Analyzer Slider, Full Wavelength Retardation Plate 530nm for Geology, Gypsum Test Plate PL03026142

Hello, I'm Steve Ross, general manager of product and marketing for Nikon. And today, what we're going to do is follow-up on some of the previous lectures, specifically on polarized light, differential interference contrast or DIC, and phase contrast. And what I'd like to do is give more of a practical view of how you actually get these techniques to actually work on the microscope, and what are the components, and how you would adjust them and troubleshoot them to get the techniques implemented for practical applications. So two of the critical components, we're going to start with polarized light in a very simple way. Polarized light, as it relates to differential interference contrast or DIC. We have what's called a polarizer and an analyzer, which is basically another polarizer, that when you cross these two, you can actually see that you get to a point of extinction, where the ligh
