FIELD: optics. SUBSTANCE: mirror adjustment device has frame 1 which carries mirror 5 installed for swinging with reference to axis coinciding with axis of sealing ring 7 laid in groove. Turn of mirror is accomplished with the aid of two pairs of adjustment screws 4 located in mutually perpendicular planes through ring 2 having spherical surface coupled to frame and mobile base 6 with conical surface coupled to mirror on which adjustment screws act. EFFECT: expanded range of turn of mirror with keeping of tightness of space of mirror. 2 dwg
