摘要： An ultraviolet (UV) catadioptric imaging system, with broad spectrum correction of primary and residual, longitudinal and lateral, chromatic aberrations for wavelengths extending into the deep UV (as short as about 0.16 nullm), comprises a focusing lens group with multiple lens elements that provide high levels of correction of both image aberrations and chromatic variation of aberrations over a selected wavelength band, a field lens group formed from lens elements with at least two different refractive materials, such as silica and a fluoride glass, and a catadioptric group including a concave reflective surface providing most of the focusing power of the system and a thick lens providing primary color correction in combination with the focusing lens group. The field lens group is located near the intermediate image provided by the focusing lens group and functions to correct the residual chromatic aberrations. The system is characterized by a high numerical aperture (typ, greater than 0.7) and a large flat field (with a size on the order of 0.5 mm). The broad band color correction allows a wide range of possible UV imaging applications at multiple wavelengths.

摘要： A means for examining the sun in monochromatic light in which the separation of the mirrors of either a catadioptric, or pure two-mirror, telescope is altered to produce a virtual object for a converging lens, termed a "forcing lens," this lens being so located between the virtual object and a narrow-band, Fabry-Perot, etalon-type, interference filter, that the convergent beam of light from the telescope passes through the interference filter at a high focal ratio, relative to the telescope's conventional focal ratio, before it traverses the forcing lens, which in turn forms the optical system's only real image, at a different, and much lower, focal ratio. Image contrast is markedly enhanced, relative to the contrast obtained by the same telescope at its conventional focus. By means of a graduated series of entrance pupils, which may be generated by a graduated series of broad-band pre-filters, a step-wise-zoom, constant-contrast, solar monochromator may be constructed. Formulas are provided for parfocalizing a series of forcing lenses. By means of such a series, real-image height may be adjusted, allowing the optimization of an eyepiece/forcing-lens combination for viewing the solar disk and surrounding prominences simultaneously, out to a considerable distance from the solar limb.

摘要： An ultra-broadband ultraviolet (UV) catadioptric imaging microscope system with wide-range zoom capability. The microscope system, which comprises a catadioptric lens group and a zooming tube lens group, has high optical resolution in the deep UV wavelengths, continuously adjustable magnification, and a high numerical aperture. The system integrates microscope modules such as objectives, tube lenses and zoom optics to reduce the number of components, and to simplify the system manufacturing process. The preferred embodiment offers excellent image quality across a very broad deep ultraviolet spectral range, combined with an all-refractive zooming tube lens. The zooming tube lens is modified to compensate for higher-order chromatic aberrations that would normally limit performance.

摘要： A compact virtual image electronic display system is provided which includes a microdisplay for producing a source object, one or more magnification optics, and a distance adjusting mechanism for adjusting a distance between the one or more magnification optics and each other or a reflective surface, the magnification of the compound magnified image relative to the source object being dependent on this distance. The system may include a distance sensing mechanism for sensing the distance between the beamsplitting magnification optic and the reflective element and communicating the distance to a control mechanism which modifies the source object in response. The system can also include a control mechanism for causing the distance adjusting mechanism to adjust the distance in response to the source object produced by the microdisplay. The system can also include a user selectable input for modifying the source object.

摘要： A solid catadioptric lens (10) includes substantially planar input surface (14), primary concave mirror 18, secondary convex mirror (22) and substantially spherical exit surface (24). The lens is composed of solid material (12) chosen according to the particular imaging application in which the lens is to be used. Radiation enters lens through input surface (14), travels through solid material (12) and is reflected off of primary mirror (18). Radiation subsequently passes internally through solid material (12) and is reflected off of secondary mirror (22). Subsequent to being reflected off of secondary mirror (22), radiation (30) passes through solid material (12) and out of lens (10) through spherical exit surface (24) and onto detector array (34) for imaging purposes.

摘要： An ultracompact complex optical device made up of a monolithic block of optical material with two opposite aspherical surfaces, the primary mirror being an aspherical annular specular concave surface and the secondary mirror being an aspherical convex or concave specular surface, circular in shape; the rays of light refract as they enter the optical material and are then reflected on the primary mirror made up of the generally convergent surface of optical material, and in the secondary mirror made up of the surface of the optical material in convergent or divergent form, once or several times, and lastly these are refracted as they leave the optical material. The device is used for application in the manufacturing of magnification lenses, eyepieces, microscopes, spyglasses, whether binoculars or telescopes, large telescopes, photographic cameras and also in any instrument or device in which non-visible radiation is used or developed.
