The invention discloses an imaging and ranging optical axis coupling optical system, which comprises a laser transmitting module, a composite prism, a common lens group, a rear lens group and a laser receiving module, wherein laser generated by the laser emission module is guided to the common lens group through the composite prism, and the common lens group reflects the laser back to the composite prism to complete laser emission; the composite prism is used for splitting the laser, one path of light is guided to the rear lens group for focusing and imaging, and the other path of light is guided to the laser receiving module for ranging, so that three optical axes of laser emission, laser receiving and imaging are coupled. The problems that the number of windows is large, the size of the device is large, and a complex focusing structure is needed to achieve visible light and infrared light dual-band parfocal due to the fact that an existing multifunctional camera product integrates the ...
