Canty was founded by John M. Canty, P.E. at the time he was involved in designing a very deep high pressure Diving Research Facility, capable of simulating ocean depths of over a mile. He found that no lighting components were available which would withstand the required pressure of 2500 PSI. Hence, it was necessary to develop a light that would permit illuminating the chamber under these conditions. Since this vessel was to be used for manned experiments, it was desirable to keep electrical components outside due to the potential fire hazard of electrical sparks in a confined environment.
This led to the development of a new type of Hyperbaric Chamber Light. The development was registered and eventually a patent was issued in 1974 for the basic concept of a fiber optical material transmitting energy through a barrier with a pressure seal.
Canty was established in 1971 to market this item because of the obvious application to recompression chambers for offshore diving and for hyperbaric oxygen chambers.
Later on, the optical systems were improved on and engineering drawings and product specifications were completed.
Presently, Canty still seeks to improve its designs and are introducing LED lights into their optical systems. Also new in their lineup are process cameras capable of automation with the use of their proprietary CantyVision Client software.
