Detailed explanation-1: -Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above). Microscopes with in-stage condenser lenses render a sharper image than those with no lens (at 400x).
Detailed explanation-2: -Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).
Detailed explanation-3: -The compound microscope may contain one or two other lenses called objective lenses. If there are two objective lenses, they are called the low-power and high-power objective lenses. The low-power objective lens usually magnifies 10 . The high-power objective lens usually magnifies 40 .
Detailed explanation-4: -CAUTION: NEVER, EVER, use the coarse adjustment knob with the high power objective. This could break the lens. Multiply the power of the ocular lens, by the power of the objective lens.
