The holophotal system of illumination for lighthouses offers several distinct advantages. It is designed to produce the brightest beam from a given flame using the smallest number of reflections and refractions. This system combines dioptric with catoptric actions, effectively utilizing the light without relying on traditional reflecting surfaces that may absorb light[1].
Additionally, the holophotal system allows for effective light distribution, where one half of the incident rays is parallelized by the lens and the other half is reflected back through the focus. This method results in a concentrated beam of light, increasing both the intensity and range compared to earlier systems[1].
