Best Answer

First focus the microscope on the lowest objective using first the coarse djustment knob and then the fine adjustment knob. Once you have it in focus, move on and do the same for the next highest objective. Continue this process until you reach the highest objective and focus it in the same fashion.

When do you use fine focus and the coarse focus knobs?

The fine focus knob is used to bring an object into fine focus, while the course focus knob is used to bring an object into approximate focus. The course focus knob should only be used on the low-power and scanning objectives of the light microscope. Using it on the high power microscope is okay, but you should be very careful. It is no recommended to use the course adjustment knob on the oil-emersion objective as it is so close to the stage and could lead to a potential break in the slide. Fine focus adjustment knob is useful to bring out the fine details in the specimen on your slide. Can be used on any of the objectives, but most receptive on the high-power and oil-emersion objectives.
