A lens barrel includes an imaging optical system including a plurality of lens groups located on an optical axis; an insertable/rotatable optical element which produces a specific photographic effect when rotated on the optical axis; and a drive mechanism including a motor which moves the insertable/rotatable optical element between an inserted position, in which the insertable/rotatable optical element is positioned on the optical axis, and a removed position, in which the insertable/rotatable optical element is removed from the optical axis by forward and reverse rotations of the motor, respectively. The drive mechanism rotates the insertable/rotatable optical element on the optical axis by the forward rotation of the motor when the insertable/rotatable optical element is in the inserted position.

A method is provided for measuring Mueller Matrix of an optical system of an exposure apparatus. Light flux from a light source is serially converted into any of a plurality of polarized light beams perpendicular to each other on Poincare sphere and is output. This polarized light beam is injected into a projection optical system or the like to be converted into a converted polarized light beam based on Mueller matrix of each optical system. With a linear polarizer or a linear phase retarder being properly inserted into an optical path of the converted polarized light beam, a light intensity is measured. Stokes parameters of the converted polarized light beam are calculated based on the measured light intensity.

A lens barrel includes a radially-retractable optical element constituting a part of photographing optical system, and is movable between a photographing position and a radially-retracted position; a biasing device for biasing the radially-retractable optical element toward the photographing position; and a swing member which is rotatable about a rotation axis extending parallel to the optical axis, the swing member being rotated so as to push the radially-retractable optical element against a biasing force of the biasing device to move the radially-retractable optical element to the radially-retracted position. The radially-retractable optical element and the swing member are mutually positioned so that a moving amount of the radially-retractable optical element per unit of rotation angle of the swing member gradually decreases as the radially-retractable optical element moves from the photographing position to the radially-retracted position.

A cam mechanism includes a cam ring, and a linearly movable frame movable supporting an optical element. The cam grooves are located at different positions in the optical axis direction and which trace a same reference cam diagram. All cam grooves are partial cam grooves each having at least one end opening at at least one of opposite ends of the cam ring, so as not to include an entire portion of the reference cam diagram. Cam followers are located at different positions at least in the optical axis direction and are respectively engageable in the cam grooves. At least one of the cam followers remains engaged in a corresponding cam groove while at least one of the other of the cam followers comes out of the end opening and is disengaged therefrom when the linearly movable frame moves to movement limit in the optical-axis direction.
