Reflector assembly, manufacturing method thereof and laser radar

The invention discloses a reflector assembly, a manufacturing method thereof and a laser radar, and relates to the technical field of laser radars. The reflector assembly comprises a substrate and a reflector arranged on the substrate. A metal connecting part is arranged on the substrate, and the metal buffer layer on the reflector is connected to the metal connecting part through a brazing process. The manufacturing method provided by the embodiment of the invention is used for manufacturing the reflector assembly. In the application, the reflecting mirror is connected to the metal connecting part on the substrate through brazing, so that the bonding strength is higher, the reflecting mirror is not easy to fall off or shift due to factors such as vibration, impact, aging or thermal expansion and cold contraction, and the stability is better. The laser radar provided by the embodiment of the invention comprises the reflector assembly or the reflector assembly manufactured by the manufacturing method, so that
