Eye safe function

Eye safe function in provided to limit the laser output according to the altitude relative to the ground. It complies with laser class 1M.

Altitude to ground < 40m : Class 1
Altitude to ground > 40m : Class 3R (NOHD *2 : < 40 m)

Depth measurement capability

At a distance of 50m from the water surface

R=1.0, absorption coefficient=0.25(1/m) > 1.4 secchi *3
R=0.5, absorption coefficient=0.25(1/m) > 1.25 secchi
R=0.2, absorption coefficient=0.25(1/m) > 1 secchi

*1 Accuracy after post-processing in the cloud service “POST-PROCESSING CLOUD”. A separate contract is required to use the service.
*2 NOHD: Nominal Ocular Hazard Distance
Distance from the laser source where the beam irradiance or radiant exposure equals the maximum allowable exposure to the eye. Laser light, however, has a spread angle, so the farther it expands, resulting in less energy per unit area. Even if the level is dangerous at the launch site, it becomes a so-called safe level below MPE at a remote location.
*3 A 30cm diameter white disc (transparency plate or secchi plate) is submerged in water, and the depth at which it becomes invisible is 1 secchi.
