collimatedbeam
A collimated beam is a beam of light or other radiation that has been focused so that its rays are nearly parallel to each other. This means that the beam spreads out very little as it travels. In an ideal collimated beam, the rays would be perfectly parallel, and the beam would not spread at all. However, in reality, some degree of divergence is always present due to the wave nature of light and imperfections in the optical system used to create the beam.
Collimated beams are produced using optical components such as lenses or mirrors. A common method is to
The primary advantage of a collimated beam is its ability to travel long distances with minimal loss
