摘要： An apparatus includes a support section which supports a further section, an optically transmissive substrate, and a dispersive section, the further section transporting plural signal components at respective frequencies along a path of travel. A plurality of optical fibers have ends fixedly coupled to a surface on the substrate. The dispersive section has a dispersive characteristic which deviates a direction of travel of each signal component by a respective different amount to optically map each signal component between the end portion of a respective fiber and the path of travel in the further section. During assembly, the fiber ends are moved relative to the surface while radiation passing through them is monitored, and then they are fixedly coupled to the surface in a selected position.

The lens system comprises an objective lens, an eyepiece lens, a plurality of lenses disposed between the objective lens and the eyepiece lens to provide the zoom function and a diffractive pattern disposed at a surface, preferably the interior surface and preferably integral therewith, of the objective lens to provide color correction at a predetermined wavelength of light passing through the objective lens. All of the lenses are preferably germanium. The diffractive pattern comprises a plurality of spaced ring-shaped steps, each ring concentric with the center of the objective lens and each step having a height equal to the predetermined wavelength for which the lens system is designed. The plurality of ring-shaped steps are formed in accordance with a known formula.

摘要： A zoom lens assembly (10) compensates optically, as opposed to mechanically, for changes in temperature. In a preferred embodiment a difference in focus between WFOV and NFOV zoom lens positions, over temperature, is minimized such that any actual shift in focus falls within the depth of focus of the zoom lens assembly. The zoom lens assembly has, along an optical axis, first and third lens elements (12,16) that are made from a first material and that have a positive power, a second lens element (14) interposed between the first and third lens elements and movable along the optical axis between a WFOV and NFOV position. The second lens element has a negative power and is made of a second material. The materials are selected such that a change in refractive index for a change in temperature of the first material is less than a change in refractive index for a change in temperature of the second material. The zoom lens assembly also color corrects incident radiation using a diffractive surface on at least one of the first and third lens elements.

摘要： An infrared lens and detector system and associated method are disclosed that utilize infrared lenses to form an internal entrance pupil at which an internal aperture stop is placed to control the intensity of infrared radiation focused on the infrared detector. In more detailed respects, the infrared lens is an assembly including a first infrared lens, a second infrared lens spaced from the first lens to form a pupil between the first and second lenses, and an aperture stop disposed proximal the pupil. The aperture stop may have a fixed diameter or may have an aperture stop that is manually or automatically adjustable depending upon the intensity of the infrared radiation being viewed. Significantly, this lens assembly may be sealed for improved performance particularly in extreme conditions. In more detailed respects, the lens assembly forms a wide-angle lens and includes a diffractive surface on the second lens to reduce color aberrations and improve performance. In another respect, the infrared lens is part of a detector system that also includes an infrared detector, a signal processor, and a display.

摘要： An optical apparatus (110) includes a base member (121) with a plurality of grooves (181-187, 191-197), and includes a respective lens (11-17) fixedly mounted in each groove. Optical filters (31-35) are mounted on the support member in predetermined locations. One such lens is fixedly secured to an input optical fiber (21), and the input fiber is used to introduce radiation into the apparatus. Several output optical fibers (22-27) are successively positioned in relation to respective lenses by a fiber positioner (302), which monitors the amount of radiation passing through the fiber being positioned, and then causes a laser (303) to fuse the fiber end to the associated lens in a selected position.
