[0023] The aforementioned stabilized laser night vision device, through the cooperation of lens module 2, imaging module 3, and charging module 4, enables long-distance observation of targets under nighttime or low-light conditions. The coordinated action of the first lens cavity 11, second lens cavity 12, main cavity 13, and charging cavity 14 ensures that the first lens group 21, second lens group 22, imaging module 3, and charging module 4 are independently arranged, positioned, and fixed, enhancing the assembly stability of these components and effectively reducing the risk of component movement or accidental detachment.
