LIDAR-Lite v3/v3HP Beam Specifications

At very close distances, less than 1 meter, the LIDAR-Lite v3/v3HP beam diameter is roughly the size of the transmit lens. For distances greater than 1m the beam diameter can be estimated using the following equation:

Distance/100

This will estimate the spot size in whatever units were used to measure the distance. The beam spread specification is ~8 milliradians or ~0.5 degrees. It should also be noted that the beam is not a circular spot, but instead is more of an oval due to the laser being a rectangular, edge emitting source. 

Laser specifications related to wavelength, mode, pulse width, etc., may be found in the owners manual.
