Underwater Lasers

A.G.O.’s compact underwater lasers are designed to be used by divers and on small ROVs or drop camera systems. They are suitable for inspection and surveys in both fresh and salt-water environments. Contact us with your requirements.

Laser penetration is limited by water conditions. Under ideal waters off the coast of Thailand, a commercial diver illuminated a target with one of our green lasers 230 ft away! Class 3R lasers have much better penetration than Class 2 and green lasers have better penetration than red lasers within each class.

A.G.O.'s lasers are tested to operate at 2 degrees Celcius, but all lasers begin to lose power below 5 degrees Celcius. Caution: consistent operation below 5 degrees Celcius is not guaranteed.

The S2000BL and S2000CL lasers use the optional brackets and mounts also available for the S2000 underwater lights and cameras.

NEW! All formats of our subsea lasers are now available in 405nm (violet) lasers in 5mW or (Class IIIB - safety glasses required) 20 mW.

All models are available in -DP 3000m rated deep water versions, with anodized aluminum housings

405 nm Sub-sea Violet Laser

Our new 405 nm sub-sea violet laser causes visual florescence while in-situ in the water column, observable when combined with a video camera monitoring systems. There are two versions of the unit, dot and line with an output of 20 mili watts. It's powered from 12 to 28 VDC via the inline RMG-2-FS connector. Pin 1, the large pin is negative (white wire) and pin 2, the small pin is the positive voltage (black wire). This unit has been tested to a depth of 200 meters. The laser is housed in a 1.5” diameter stainless dairy tube. The lens is made from 1.5” square acrylic plastic with a wavelength pass down to 300 nanometres. The 405 nm lasers has a centre wavelength of 405 +- 5 nanometres, therefor our standard poly carbonate lens will not work due to an internal UV barrier starting at 403 nanometres. The line laser is aligned across the diagonal of the square lens to provide maximum spread of the beam. It has been noted during tests that some biological organisms change from brown/ green to red and that urine in water changes to a green colour. It is suggested that oil in water should have florescence around the colour yellow, however more empirical testing is required.

The suggested method of installation is to mount the line laser under the camera pointing in a downward and forward direction creating a fan effect at the bottom of the video screen. If any colour changes are noted during a towed body survey, stop and take a water sample, something unusual is happening and should be examined.
