摘要： A zoom lens includes an aperture diaphragm, and a plurality of lens units including a negative lens unit arranged on a light incident side of the aperture diaphragm, the zoom lens being configured to make variable a focal length by changing an interval in the plurality of lens units. The negative lens unit includes a negative lens having a radial type refractive index distribution and a concave surface on the light incident side. The negative lens has a wavelength dispersion distribution in which a differential value is negative on an optical axis of the zoom lens, and the differential value increases at a position that is more distant from the optical axis.

摘要： The variable focus lens of the present invention changes the refractive power by changing each of the shapes of a first interface formed by a first liquid and a second liquid that have refractive indices that differ from each other and a second interface formed by the second liquid and a third liquid that have refractive indices that differ from each other. Thereby, this variable focus lens changes the first interface and the second interface such that the sign of the refractive power of the first interface and the sign of the refractive power of the second interface differ from each other.

摘要： The image display apparatus includes first and second display elements respectively displaying first and second original images, and an optical system presenting an enlarged combined image of the first and second original images with first and second light fluxes from the first and second display elements. The optical system includes at least one reflective surface. When a cross-section of the optical system on which optical paths of the first and second light fluxes are turned by reflections at the reflective surface is defined as a decentering cross-section, the first and second original images correspond to different view angles in the decentering cross-section. Light flux components respectively included in the first and second light fluxes and introduced to a same image point in the enlarged combined image are overlapped with each other on an exit pupil plane.
摘要翻译：图像显示装置包括分别显示第一和第二原始图像的第一和第二显示元件以及呈现来自第一和第二显示元件的第一和第二光束的第一和第二原始图像的放大组合图像的光学系统。光学系统包括至少一个反射表面。当在第一和第二光束的光路被反射表面上的反射转动的光学系统的横截面被定义为偏心的横截面时，第一和第二原始图像对应于不同的视角偏心横截面。分别包括在第一和第二光束中并被引入到放大的组合图像中的相同图像点的光通量分量在出射光瞳平面上彼此重叠。
