Abstract
To keep the aperture diameter of light emitted from an optical system device constant and to suppress the heat generation of an aperture diaphragm member.SOLUTION: The aperture stop member 20 is disposed on the optical path between the collimator lens 12 and the condenser lens 13, and narrows the aperture diameter of the light. The aperture stop member 20 includes a transmission unit 25 and a deflection unit 26. The transmission part 25 transmits light. The deflector 26 deflects light radially outward of the transmission part 25. The damper member 30 is arranged so as to absorb the light deflected by the deflector 26.SELECTED DRAWING: Figure 2
