The TETRA subsea laser module is a compact, rugged solid state subsea laser that has been designed for a variety of underwater highlighting and identification tasks, or when used in pairs, for scaling and ranging operations. Two or more units can be mounted a known distance from one another and will produce red dots on the targets at an equivalent spacing such that accurate measurements can be taken.
The TETRA laser module is a self-contained solid-state subsea laser pointer which is categorized as a Class 3 laser product meaning no specialized training is required to operate the unit. The laser can be powered from a 9-30V DC supply and is equipped with over voltage and reverse polarity protection. These units are available as standard in a hard anodized aluminum housing which is depth rated to 1000m. Other housing materials for deeper water applications are available on request.
