Eye Safety - Safran LRF 3013 Manual

LRF 3013 Integrator Manual
It is recommended to use 2 separate windows, one for the receiver channel and one for the transmitter
channel. Both windows should be sufficiently flat. A window with poor flatness will lead to a boresight
issue, resulting in a reduction of achievable range performance.
In addition, the optical Rx & Tx channels must be optically isolated from each other. This is required to
prevent optical cross talk between both channels (scattered laser light from transmitter to receiver). The
two windows have to be aligned with a wedge error of less than 10 seconds of arc.

To avoid sunlight reflections on the front window which can be seen by others, a tilt angle of 5°-10°
downwards can be implemented. The LRF Module itself does not require a tilt angle, range performance
can be achieved with a 0° tilt angle.

4.4 Eye Safety

LRF 3013 meets Class 1 eye safety requirements according to IEC 60825 and ANSI Z136.1. The eye
safety of the host system has to be tested and guaranteed at the system level by the OEM system
integrator. To meet Class 1 requirements on system level, mind the maximum measurement repetition
rate of 2 Hz (details can be found in chapter 6.2.2).
