Detailed explanation-1: -To get the total magnification level you must multiply the magnification of the ocular lens by the magnification of the objective lens. So, if you are viewing your slide under the 40x objective lens you would multiply that by the 10x of the ocular lens for a total magnification of 400x.
Detailed explanation-2: -Coarse and fine adjustment The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.
Detailed explanation-3: -CAUTION: NEVER, EVER, use the coarse adjustment knob with the high power objective. This could break the lens.
Detailed explanation-4: -Use the Fine Focus Knob to bring the image into focus. When using 10x and 40x objectives, use ONLY the fine focus knob so that you don’t scratch a lens or break a slide.
