Most AP readers will have seen a Fresnel lens, but few will actually own one - or know why they might need one. You'll have seen them on the sides of lighthouses: with their concentric grooved rings, they turn the general spread of the lamp into the straight beams that streak out over the sea. Placing a Fresnel lens in front of a photographic light does the same thing: it collimates the light into a beam to produce an effect like a spotlight, but softer.
