One of the major challenges in locating people lost at sea, both day and night, is that they are incredibly difficult for rescuers to spot against the cold, dark waters. However, with infrared technology, the contrast between the cold water and a person's warm body makes them stand out immediately. Umicore's DLC coating is specifically designed for marine applications, ensuring our lenses are resistant to salt, fog, spray and water ingress, making them ideal for these harsh environments.
