摘要： A laser ranging device (1) and a robot. The laser ranging device (1) comprises a transmitting unit (11) and a receiving unit (12). The transmitting unit (11) comprises a transmitter (111) that is used for transmitting a pulsed laser to a target object to undergo ranging and a transmitting lens (113) that is used for allowing the transmitted. pulsed laser to pass through. The receiving unit (12) comprises a light detector (121) that is used for receiving the pulsed laser reflected from the target object and a receiving lens (123) that is used for the reflected pulsed laser to pass through. The light detector (121) is disposed by means of being encapsulated in an encapsulating module (124), the encapsulating module (124) being located behind the receiving lens (123) and opposite the receiving lens (123), and one side thereof facing the receiving lens (123) being constructed as an extinction surface.
