PROBLEM TO BE SOLVED: To provide optical equipment that can simplify an adjusting process relating to lenses and that can suppress deterioration of a coupling efficiency of a laser beam to an optical component, in the optical equipment in which a semiconductor laser, an optical component for introducing light emitted from the semiconductor laser, and a lens for optically coupling the semiconductor laser with the optical component are arranged in a housing. SOLUTION: In the optical equipment, there are arranged in a housing a semiconductor laser 1, an optical component 4 for introducing light emitted from the semiconductor laser, and a lens for optically coupling the semiconductor laser with the optical component. The optical equipment is characterized in that a holding mechanism 3 for holding the lens is composed of a holding member and a rotary tube arranged rotatably relative to the holding member, with the lens arranged in the rotary tube eccentrically to the rotary axis of the rotary tube, that, in the housing, a groove is formed vertically to the optical axis direction of the lens, and that the holding member is positioned by the groove 20.
