The parabolic acoustic sensor AA PR400 is fitted with a class 2
laser.
The available laser beam is therefore only within the visible
spectral range (650 nm). It is not harmful to the eye in the event of
brief periods of exposure (up to 0.25 sec.). Longer periods of
exposure are prevented by the natural corneal reflex.
