The invention relates to the technical field of optical machines and provides an optical mirror frame device. The device comprises a mirror frame body, a cooling unit and a vibration absorption unit. The cooling unit comprises a cooling channel arranged in the mirror frame body. The vibration absorption unit is a power vibration absorber arranged in the cooling channel. The damping medium of the power vibration absorber is a cooling medium injected into the cooling channel. According to the invention, the power vibration absorber controls vibration, the initial amplitude of a main vibration system is small, and the interference of a vibration source is small. On the basis, the power vibration absorber is internally arranged in the cooling channel of the cooling unit, and the cooling medium in the cooling channel is used for heat dissipation of the mirror frame body and optical elements arranged on the mirror frame body, is also used as the damping medium of the power vibration absorber and is capable of cooling the power vibration absorber, so that the vibration absorption function and the cooling function are integrated on the basis that the complexity of the optical mirror frame structure is not enhanced, and the integration degree of the optical mirror frame is improved.
