PURPOSE: An apparatus for controlling a lens position of an optical field is provided to control a phase difference in detail by controlling a position and an angle of a lens by means of a plurality of brackets, a set screw, and a spring. CONSTITUTION: An apparatus for controlling the lens position of an optical field comprises a lens unit(10) arranged on a predetermined light path of an optical system and a position controlling unit. The position controlling unit supports and compresses both ends of the lens unit(10) and controls the position of the lens unit(10). The position controlling unit comprises a fixed bracket(20), a moving bracket(30), an assembling bracket(40), a clip components(50), a first control unit, and a second control unit. The moving bracket(30) is formed to the A and B direction which are each a predetermined control direction so as to be capable of sliding to the fixed bracket(20). The assembling bracket(40) is coupled to the moving bracket(30) so as to be capable of assembling. The clip components(50) flexibly compresses and supports the lens unit(10). The first control unit is installed between the fixed bracket(20) and the moving bracket(30) and performs the sliding on the moving bracket(30) to the A and B direction. The second control unit is installed between the moving bracket(30) and the assembling bracket(40).
