LMNI Subsea Laser Module


The LMNI range of general-purpose, subsea laser line modules were specifically designed for maximum flexibility and reliability; supporting underwater laser imaging, inspection, survey and construction applications.


High-performance diode technology combines with a patented beam-shaping optical prism to generate a highly uniform sheet of light; eliminating optical hot-spots and providing optimum contrast when observed on camera.  This reduces eye-safety risk, and lowers cost of operation compared to diffractive or gaussian-type laser projectors.


LMNI blue-green lasers are highly visible over long distances in seawater due to minimal attenuation and are essential for enhancing vision in turbid waters; the contrast-reducing effects of light scattering can be significantly reduced.  Deployed globally on ROVs, trenchers, oceanographic landers and seabed mapping vehicles; multiple lasers are also used as a visual alignment tools, datums for MBES seabed surveys or to capture 3D underwater point-cloud models when used with Savante cameras.


A range of alternative violet, red and infrared laser modules and a variety of beam-shaping optics are also available for custom applications.



Key Features:

  • Robust, general-purpose 60mW subsea laser module.

  • Ultradeep rated - 4000m depth rating.  (6000m option).

  • Digitally controlled variable intensity; PWM or TTL option.

  • Onboard thermal management.

  • High definition projection enables optimal precision measurement accuracy.

  • OEM or optional “laser on” indicator for IEC compliance.

  • High-efficiency direct diode laser technology.

  • Reverse-polarity protected, wide input voltage range (18-30VDC) enables easy integration.

  • Anti-reflection coated sapphire windows; delivers high-definition imaging performance, reduces stray light and best scratch resistance for longer life.

  • Available with a range of diffractive projection optical heads for a variety of structured light projection options (points, arrays, grids, circles, crosshairs, company logos).

  • Available in violet, blue, green, red and infra-red wavelengths.



Optional Extras:

  • Savante VOXEL 3D underwater machine-vision scanning software
  • Mounting brackets
  • Battery packs
