The antonyms for the word collimated are divergent, scattered, and unfocused. Collimated refers to light rays that are parallel and therefore focused in the same direction, usually through a lens or prism. In contrast, divergent rays spread out in different directions, resulting in a wider and less focused beam. Scattered implies a random and disorganized distribution of light, without any specific direction or purpose. Finally, unfocused suggests a lack of clarity, sharpness, or precision, whether due to a faulty lens, a blurry image, or a distracted mind. These antonyms highlight the importance of proper alignment, concentration, and attention to detail in various contexts, from optics to psychology to communication.
