In optical systems, a lens is typically used for final focusing to converge light rays to a single point or plane. The focal length of the lens determines the distance at which it needs to be placed to achieve proper focus. Other methods for final focusing include mirrors, phase plates, or diffractive elements in certain applications.
The coarse adjustment knob should be used first to bring the specimen into general focus. Then, the fine adjustment knob can be used for precise focusing.
