The invention relates to a handheld low-light binocular telescope with window penetrating viewing and photographing functions. The handheld low-light binocular telescope comprises a low-light object lens component, an eye lens component, a time sequence control panel component, a laser device component, an image intensifier component, a CCD component and a power supply module. The beneficial effects of the handheld low-light binocular telescope are that (1) the handheld low-light binocular telescope has a video output interface so that high-resolution video signals can be provided; (2) a target can be observed through window glass at night; and (3) the handheld low-light binocular telescope has certain penetration capacity, the influence of atmospheric backscattering can be eliminated by using the range gating technology, and the image of the target hiding behind a camouflage net and a smoke screen can be acquired.
