摘要： A device for adjusting an optical axial position of a lens is disclosed. The device includes a lens frame for mounting at least one lens, a lens frame supporting member rotatably engaged with the lens frame via screw threads for supporting the lens frame in such a way that the lens frame is rotatable relative to the lens frame supporting member, coupled to a stationary member for adjustment of the optical axial position of the lens relative to the stationary member. Set screws are provided for selectively locking the lens frame to the lens frame supporting member at one of a plurality of stepwise, predetermined, relative angular positions between the lens frame and the lens frame supporting member after the optical axial position of the lens has been adjusted relative to the lens frame supporting member. Since the lens frame can be locked to the lens frame supporting member at one of the plurality of stepwise, predetermined, relative angular positions by use of the set screws after the optical axial position of the lens has been adjusted, it is possible to improve the locking reliability and simplify the structure of the adjusting device.
