*The azimuth and pitch angles of the large lens can be adjusted.
| On the bottom surface of the mirror, three screws with resin heads are used to fix it, which is convenient for holding lenses of different thicknesses； |
| The differential differential head with a resolution of 0.0005mm is adopted to realize the precise adjustment of the Angle； |
| The rotation axis of the omnidirectional frame intersects at the center of the front surface of the optical lens. When adjusting the omnidirectional frame, only the Angle of the beam is changed, not its length. |
