Total magnification is the same, but the detail, the resolution, will be better with the 40x objective. To illustrate, a 40x objective and a 10x eyepiece will result in a higher resolution (more detailed) image than a 20x objective and a 20x eyepiece. All an eyepiece can do is magnify the resolution that is already provided by the objective. (ii) Another thing to consider is that microscope resolution which is the ability to see close but separate points as distinct comes from the objective lenses, not from the eyepieces. Most educational-quality microscopes have a 10x (10-power magnification) eyepiece and three objectives of 4x, 10x & 40x to provide magnification levels of 40x, 100x and 400x. The total magnification of the microscope is calculated by multiplying the magnification of the objectives, with the magnification of the eyepiece. Gram-Negative Bacteria and Endotoxins Like their Gram-positive counterparts, Gram-negative bacteria account for a wide variety of different species. These can lead to multiple types of infections including anthrax, diphtheria, and listeriosis.
