    • An illumination apparatus includes: first and second lamps; and a combining mirror configured to combine emitted lights from the first and second lamps The combining mirror includes first and second reflection surfaces opposing the first and second lamps respectively, being abutted vertically with respect to each other, whereby forming an edge. Since optical axes of the first and second lamp are respectively inclined with respect to a reference axis being orthogonal to a system optical axis of the illumination apparatus, central axes of the lights from the first and second lamps are incident on a downstream optical system in a state of being slightly inclined with respect to the system optical axis after being reflected on the first and second reflection surfaces respectively.
    • 照明装置包括:第一和第二灯; 以及组合镜,其被配置为组合来自第一和第二灯的发射光。组合镜包括分别与第一和第二灯相对的第一和第二反射表面,其相对于彼此垂直抵接,由此形成边缘。 由于第一灯和第二灯的光轴分别相对于与照明装置的系统光轴正交的基准轴倾斜,所以来自第一和第二灯的光的中心轴入射在下游光学系统中 在分别在第一和第二反射面上反射之后相对于系统光轴稍微倾斜的状态。
