Our subsea lasers use a <5 mW Class III-A semiconductor laser diode. The lasers have a long life, compact size, and wide input voltage. Applications include measurement, scaling, reference pointing, and aligning.

Both of our Micro SeaLaser® and SeaLaser® 100 lasers are available with a dual mounting bracket to provide parallel beams. The brackets can mount most SeaCam® cameras.


The compact Micro SeaLaser features a sapphire port, a titanium housing, 6,000 m depth rating, and a <5 mW Class III-A semiconductor laser diode. Uses include underwater aiming, scaling, and alignment. This subsea laser has a long life, compact size, and wide input voltage.

A mounting bracket is available to fit two lasers and a SeaCam. The two lasers are 10 cm apart and use either dots or lines to add scale to video or photographic images.
