3 Communication Protocol
When the N10 PLUS is working, each set of data is output through the
communication interface. The output data has uniform message formats. If you
need the detailed communication protocol, please contact LSLiDAR support.
4 Optical Features
4.1 Laser Feature
Dependent on a 905 nm laser, N10 PLUS emits high-frequency pulsed lasers
through the optical assembly, receives the laser signal through the optical
assembly, and completes the photoelectric conversion by the receiver board.
The distance value calculation is completed by the master control chip and the
laser optical parameters are as follows:

4.2 Light Spot
The light spot of the N10 PLUS lidar is a vertical oval. Its vertical divergence
angle is 11.4 mrad, and the horizontal divergence angle is 8.4 mrad. The spot
size at any distance can be calculated by multiplying the divergence angle by the
distance.
For example, the calculation of a spot at 10 m is as follows
Vertical direction at 10 m: 10*11.4*10
-3
=114 mm
Horizontal direction at 10 m: 10*8.4*10
-3
=84 mm
