EDITORS COMMENTS
This engraving from the 19th century showcases a Fresnel echelon or lighthouse lens in intricate detail. The image depicts a plano-convex lens at point A, surrounded by carefully calculated glass rings that share the same focus as the central lens. Mirrors M and N are strategically placed to redirect any escaping light back into the primary beam, ensuring maximum efficiency. The precision and complexity of this optical mechanism is truly remarkable, highlighting the ingenuity and innovation of lighthouse optics during this era. Lighthouses played a crucial role in guiding ships safely through treacherous waters, and lenses like these were essential for providing a reliable source of light for sailors navigating at night. The engraving beautifully captures the elegance and functionality of this revolving lighthouse lens, showcasing its ability to regulate and control light with incredible accuracy. This piece serves as a testament to both the artistry and scientific advancements of the time, offering viewers a glimpse into the world of optical technology in the 19th century. Overall, this print is not only visually striking but also serves as a fascinating historical artifact that sheds light on the importance of lighthouses in maritime safety.
