In our poster, in the location of the red LED focus, the Laser was used as an illustration of a technology based on light and extremely important in everyday life.
There are predominantly 4 types of lasers, each with different features and utilities, they being the following:
Laser Type 1 - Use in readable (bar code), or CD's;
Laser Type 2 - Use on DVDs;
Laser Type 3 - Use in medical technology (LASIK);
Laser Type 4 - Military Use (Laser Weapons).
Laser plays a key role in diversa utilities and it presents very special characteristics such as the fact of being monochromatic, that is, having with a wavelength very well defined, and collimated, which means parallel propagation of light beams. The collimation process is represented on the poster along the collimator, which is by the prism.
