Camera systems used for deep-sea video missions require mechanical housings, which can withstand the immense pressures of the ocean. These housings are generally pressurized-air canisters. The size, weight and cost of these housings increase rapidly with the ocean depth of the mission. The risk of catastrophic implosion and resulting bodily harm to divers also increases with depth. This paper presents a liquid-filled camera system which reduces these risks and limitations by eliminating the need for such air-filled housings in a novel lens design.
