    摘要： A dual field optical system 20 comprises an objective A, B, which forms an intermediate image 10 and a relay E,F, which transfers radiation to a focal plane 12. The objective A, B comprises a primary mirror A and a secondary mirror B arranged in the form of a Cassegrain system and is rendered dual-field by the provision of an alternative primary mirror A 1 which is axially movable between in-use and out-of-use positions. The primary mirror A forms part of a housing J for a linear actuator 15 which is connected by co-axial rods 14 to the alternative primary mirror A 1 so that the system is both compact and of low mass due to symmetry.

    摘要： 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.

    摘要： The present invention provides a lens system and/or a method of imaging onto an imaging detector. The lens system and method are used in focusing substantially parallel incident light onto the said detector. The lens system comprises: (a) a concentric spherical Cassegrain-like system of two mirrors; (b) a concentric spherical focal reducer; (c) a transfer lens system which combines the concentricity of the Cassegrain-like system of two mirrors and of the contrentric spherical focal reducer by imaging the first centre of concentricity that is of the system of two mirrors onto the second centre of cencentricity, that is, of the focal reducer to thereby provide a single optically cencentric system which combines their advantages. Also present in the system are: (d) means to correct the sum of the spherical aberation of all the spherical mirros in the entire system and (e) an aperture stop.

    摘要： An all-reflective telescope has, in order, a positive-optical-power primary mirror, a negative-optical-power secondary mirror, a positive-optical-power tertiary mirror, a negative-optical-power quaternary mirror, and a positive-optical-power field lens. The mirrors and lens are axisymmetric about a beam axis. The light beam is incident upon an infrared detector after reflecting from the quaternary mirror. A cooling housing encloses the detector and the field lens, but does not enclose any of the mirrors. An uncooled warm-stop structure outside of the cooling housing but in a field of view of the detector is formed as a plurality of facets with reflective surfaces oriented to reflect a view of an interior of the cooling housing back to the interior of the cooling housing.
