Rainbows, mirages, the color of what we see, laser light, X-rays, etc. are all typical situations with which we live and whose explanation is based on optical theories. Sometimes they seem complicated, but they are all based on the combination of simple phenomena.

Nowadays, communications are carried out thanks to light. We convert electrical signals into light signals, which are associated with less loss in their path. The aging of magnetic materials has had an important influence on the loss of information. In addition to greater storage, photosensitive elements show less frequent deterioration.

Phenomena such as total reflection have gone from being mere proven theoretical facts to being the driving force behind today's well-known "optical communications". Magnetic read heads have given way today to laser reading, and information storage has replaced the use of ferromagnetic devices with that of photosensitive elements.

The Set for the Study of Optics application, "FOP", has the objective of the study and understanding of simpler phenomena on which other much more complicated ones are based. In this case, focusing on: reflection, refraction, transmission, absorption and measurement of light intensity (irradiance).
