Reflective objective, wideband objective optics with mirrors and optical imaging system with refractive lenses and broadband optical imaging system with two or more imaging paths
Reflective objective, wideband objective optics with mirrors and optical imaging system with refractive lenses and broadband optical imaging system with two or more imaging paths
An optical system may include an objective having at least four mirrors including an outermost mirror with aspect ratio 20:1 and focusing optics including a refractive optical element. The objective provides imaging at numerical aperture 0.7, central obscuration 35% in pupil. An objective may have two or more mirrors, one with a refractive module that seals off an outermost mirror's central opening. A broad band imaging system may include one objective and two or more imaging paths that provide imaging at numerical aperture 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.
