OMAX 20X Plan Achromatic Objective for Compound Microscopes

the nomenclature on an objective lens and cover what some of the properties are and what information is printed on the front of that lens. So, the objective lens, as we've talked about before is really the most important part of the optical system. Also one of the more expensive parts of an optical system. The information on the lens, on the top you can see the manufacturer, it'll tell you the aberration correction for example, here it says "Plan Apo," and that stands for "Plan" flatfield correction, and "Apo" standing for apochromatic correction, so a very broad range of wavelengths from the violet to the red. Okay, the magnification, which is shown here as 60x is printed, as well as the color code, in our case, blue, for 60x lenses. So all 60x lenses are going to have a blue band around them. And then it shows you a slash, and a 0.95, that's the numerical aperture of the lens. The lig
