摘要： An object of the present invention is to provide a lens device that is configured such that a first optical-system and a second optical-system are combined to be concentric and that is capable of individually adjusting the light-amount of each optical-system and individually performing focus adjustment on each optical-system. The lens device, which is configured such that the optical-systems are combined to be concentric, comprises a first stop that adjusts a light-amount of the first optical-system and a second stop that adjusts a light-amount of the second optical-system. Thereby, it is possible to adjust individually the light-amounts of the optical-systems. Further, the first optical-system is provided to be movable along the optical axis L together with the first stop, and the second optical-system is provided to be movable along the optical axis L together with the second stop. Thereby, it is possible to individually perform focus adjustment on the optical-systems.

摘要： A stop mechanism, including: diaphragms; a reception receiving the diaphragms; a cam rotating the diaphragms to change an aperture diameter; and an interlocking arm interlocking with rotation of the cam and arranged on a radially outer side of the cam to rotate the cam from an outside of the stop mechanism. The diaphragms each include: an arc portion defining the aperture diameter and being received in the reception at maximum aperture; and a light-blocking projection formed on the arc portion to block light outside the aperture diameter. The reception includes cutouts for allowing the light-blocking projection to project outside at the maximum aperture. The interlocking arm is located at a position where the light-blocking projection does not overlap in a circumferential direction, and the light-blocking projection moves into the reception while the interlocking arm moves in the circumferential direction in which the aperture diameter is reduced.
