The laser ranging device comprises a measurement signal transmitting device used for transmitting measurement signals, a green light indication transmitting device used for transmitting indication green light, and a measurement signal receiving device used for receiving the measurement signals; the optical path of the green light indication transmitting device and the optical path of the measurement signal transmitting device share the same axis, or the optical path of the green light indication transmitting device and the optical path of the measurement signal receiving device share the same axis.

Description

technical field [0001] The invention relates to the technical field of laser ranging, and relates to a laser ranging device, in particular to a ranging device with a green light indicator. Background technique [0002] With the development of laser technology, laser ranging has been widely used in many industries, such as surveying and mapping, home improvement, construction, outdoor sports, etc. For the 100-meter laser distance measuring device, the red light source is generally used as the measurement signal. Although the measurement target can be well distinguished in the case of dark light, it is difficult for the human eye to distinguish in the case of strong ambient light. The red light measures the target point. [0003] The human eye is more sensitive to green light than red light, and is more sensitive to green light indication, thus ensuring safety. For machines with green light indicators in the prior art, the green light is generally parallel to but separated f...
