The utility model is suitable for the technical field of laser scanning, and provides a reflector type scanning device and a laser radar. The detection receiving units and the laser emitting units are distributed at intervals; the reflecting mirror unit comprises a condensing reflecting mirror and a collimating reflecting mirror arranged in the middle of the condensing reflecting mirror, and the reflecting surfaces of the condensing reflecting mirror and the collimating reflecting mirror are curved surfaces; the collimating mirror is obliquely arranged relative to the optical axis of the laser emitting unit so as to collimate and reflect a first light beam emitted by the laser emitting unit to a target area; and the condensing mirror is obliquely arranged relative to the optical axis of the detection receiving unit so as to reflect and focus the second light beam reflected back from the target area to the detection receiving unit. In the embodiment of the utility model, the number of optical parts is reduced,
