Novasub has a range of underwater lasers with various power consumption and illumination level.

Novasub developed a series of lasers that are very compact, rugged and cost-effective subsea lasers. Available as a Laser Dot Green 5 mW (NSLDG-1) and a Laser Line Green 5 mW (NSLLG-1). Both formats have been designed for a wide range of subsea pointing, scaling and ranging applications.

A Class 3B laser is hazardous if the eye is exposed directly, but diffuse reflections such as those from paper or other matte surfaces are not harmful. Protective eyewear is typically required where direct viewing of a class 3B laser beam may occur.

Brackets are available to hold two NSLDG – Novasub Laser Dot Green and an underwater camera. The NSLDG-lasers produce two parallel laser beams which may be viewed on the camera monitor and can be used to estimate the distance to an object with reasonable accuracy.
