Detailed explanation-1: -Focus the microscope by turning the course adjustment knob and then the fine adjustment knob which are both located on the right side of the microscope. Turn the knobs until the specimen comes into focus.
Detailed explanation-2: -The last common issue is the out-of-focus image. If the image is blurry it is most likely out of focus like this one. Solution: Try to focus most on the item of concern. Most microscopes have two focus knobs the first for coarse focus, and a second for fine focus.
Detailed explanation-3: -Use the focus knob (4) to place the sample into focus and readjust the condenser (7) and light intensity for the clearest image (with low power objectives you might need to reduce the light intensity or shut the condenser).
Detailed explanation-4: -Slowly turn the coarse adjustment so that the stage moves down (away from the slide). Continue until the image comes into broad focus. The turn the fine adjustment knob, as necessary, for perfect focus. Move the microscope slide until the image is in the center of the field of view.
