LIFL-11
A multi-wavelength LIF lidar that reads the upper water layer from a vessel or a small aircraft. At a station it records the full 48-band echo spectrum in about fifteen seconds, and underway it streams four selected bands at up to 10 Hz. It comes in two excitation models, 355 + 532 nm for chlorophyll, CDOM, and suspended matter, or 266 + 532 nm for oils, phenols, and tryptophan.
- Phytoplankton & pigments Chlorophyll-a from 0.01 to 1000 mg·m⁻³, plus phycoerythrin, phycocyanin, and pigment index, each read from its own fluorescence return
- Dissolved organic matter CDOM and FDOM, fulvic and humic acids, and the organic signature of sewage
- Hydrocarbons & oil Fuels, diesel, crude, and oil-in-water emulsions, fingerprinted by UV excitation at 266 nm
- Marine litter & plastics Polyethylene, polypropylene, wood, leaves, seagrass, and surface foam, separated by their fluorescence signatures
- Suspended matter Mineral matter and suspended sediment from 0.1 to 200 g·m⁻³ along the survey track
- And more across the spectrum Phycoerythrin and phycocyanin, bacteriochlorophyll, tryptophan and phenol markers, methane seeps
mFL-12
Active fluorescence monitoring that runs unattended, day and night, at 1.75 kg
At 1.75 kg this is the most compact hyperspectral LIF lidar the company knows of, with a single 405 nm excitation and reception across 405–880 nm. An ON/OFF technique alternates laser-on and laser-off readings and subtracts the sunlight, so the measurement holds day and night. It runs unattended on buoys, piers, and vessels, reading chlorophyll-a, CDOM, suspended matter, and oil films on the surface. TRL 7–8, field-tested with ESA at Venice in 2025.
- Chlorophyll & CDOM Continuous chlorophyll-a and CDOM from a fixed or a moving surface platform
- Suspended matter Tracks suspended-sediment concentration at outfalls, river mouths, and port basins
- Oil films & emulsions Oil films and oil-in-water emulsions, read from above the surface
- Day-and-night operation The ON/OFF laser technique isolates the fluorescence and cancels ambient sunlight
mHR-2
Measures the above-water Rrs a satellite estimates, from the surface and free of the atmosphere
The only instrument in the lineup that carries no laser. A motorised head cycles through downwelling irradiance, sky radiance, sea-surface radiance, and a dark reading, returning Rrs across 320–880 nm. Reading from the surface leaves the atmosphere out of the retrieval, which is what makes the number usable as a satellite match-up. Developed in the OQOMETHI project and field-tested with ESA at Venice in 2025.
- Above-water Rrs Interleaves downwelling irradiance, sky radiance, and sea-surface radiance with dark-current auto-calibration
- Satellite match-up Derives the same Rrs a satellite estimates, for cal/val pairing alongside the active LIF measurement
- Sun-glint rejection The 40° sky and 140° sea-surface geometry, both from zenith, minimises surface glint
- Autonomous operation Runs unattended with automatic upload to cloud storage
