What Do The Numbers On A Microscope Objective Mean? Microscope objective lenses will often have four numbers engraved on the barrel in a 2×2 array. The upper left number is the magnification factor of the objective. For example, 4x, 10x, 40x, and 100x. The upper right number is the numerical aperture of the objective. What
What Is The Lowest Power Objective Lens? A scanning objective lens provides the lowest magnification power of all objective lenses. 4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x. What is the difference
What Is The 4X Objective Lens Called? The 4X lens is called the scanning or low power lens. It has the widest field of view, allowing you to look at large parts of the specimen, and the greatest depth of field. The 10X lens is sometimes called medium power because it produces mid-range magnification. What
