US09052494B2 Optical imaging system with catoptric objective; broadband objective with mirror; and refractive lenses and broadband optical imaging system having two or more imaging paths 有权
具有反射目标的光学成像系统; 宽带客观镜面; 以及具有两个或更多个成像路径的折射透镜和宽带光学成像系统

Optical imaging system with catoptric objective; broadband objective with mirror; and refractive lenses and broadband optical imaging system having two or more imaging paths
Abstract:
An optical system may include an objective having at least four mirrors including an outermost mirror with aspect ratio 0.7, central obscuration 0.7 and field of view >0.8 mm. An optical imaging system may comprise an objective and two or more imaging paths. The imaging paths may provide two or more simultaneous broadband images of a sample in two or more modes. The modes may have different illumination and/or collection pupil apertures or different pixel sizes at the sample.
Abstract(Chinese):

光学系统可以包括具有至少四个反射镜的物镜，其包括具有纵横比<20:1的最外镜和包括折射光学元件的聚焦光学元件。 该目标提供数值孔径> 0.7，瞳孔中心遮蔽<35％的成像。 物镜可以具有两个或更多个反射镜，一个具有折射模块的反射镜，该折射模块密封最外镜的中心开口。 宽带成像系统可以包括一个物镜和两个或更多个在数值孔径> 0.7和视场> 0.8mm处提供成像的成像路径。 光学成像系统可以包括物镜和两个或更多个成像路径。 成像路径可以以两种或更多种模式提供样本的两个或更多个同时宽带图像。 这些模式可以在样品处具有不同的照明和/或收集光瞳孔径或不同的像素尺寸。
