The invention proposes a lidar device 100 for a vehicle. The lidar device 100 comprises: a transmitter 105 for emitting at least one laser beam 115 on a transmission path 110; and a receiver 135 for receiving the at least one reflected laser beam 125 on a receiving path 130. Furthermore, the lidar device 100 comprises a rotating mirror for deflecting the laser beam 115 passing through the transmission path 110 into the field of view 120 and for deflecting the laser beam 125 reflected in the field of view 120 onto the reception path 130. The rotating mirror is arranged between the transmitter 105 and the receiver 135 and separates the transmission path 110 and the reception path 130. The rotating mirror is designed as a polygon prism 117 and has at least one mirror surface for deflecting the laser beam 115 passing through the transmission path 110 into the field of view 120 and for deflecting the laser beam 125 reflected in the field of view 120 onto the reception path 130. The laser beam 125 emitted through t
