The invention relates to a laser range finder, a prism and an optical transmitter module, comprising: a prism seat; an optical transmitter for emitting or receiving invisible light beams, having pins and emitting or receiving along the optical axis direction Light beam; prism group, the beam of invisible light enters and leaves the prism group, the prism group is fixed in the prism seat, and has a bevel, and the bevel is exposed from the prism seat; driving printed circuit board, located above the bevel, light transmitter The pins of the driving printed circuit board are electrically connected to the driving printed circuit board after being bent, and the driving printed circuit board and the optical axis direction form a first angle; the shielding cover is welded on the driving printed circuit board; and the fixing component is connected to the prism seat, And the driving printed circuit board is fixed, and the fixing component is provided with an escape hole through which the light transmitter is exposed. The scheme effectively utilizes the size and shape of the limited space, has a compact structure, can adjust the focal length and position of the optical transmitter, and is simple and easy to operate.
Description
technical field [0001] The present invention relates to laser ranging technology, and more particularly, to a laser ranging instrument, a prism and an optical transmitter module thereof. Background technique [0002] figure 1 is an optical path diagram of a known laser range finder 10, which is described in the Chinese patent application with the application number of 201610165479.3. like figure 1 As shown, the laser rangefinder 10 includes a transmitting tube and a receiving tube, and a first optical system 100 and a second optical system 200 are respectively arranged in the transmitting tube and the receiving tube. The first optical system 100 includes an eyepiece group 101 , a prism group 102 , a focusing lens 103 , and an objective lens group 104 in sequence. The second optical system 200 sequentially includes an eyepiece group 201 , a prism group 202 , a focusing lens 203 , and an objective lens group 204 . After the visible light is imaged by the objective lens gro...
