A spectrometer apparatus includes a refractor element, a slit, a detector, a diffraction grating, and a corrector lens. The refractor element includes a rear surface and a front surface. The slit provides an optical path to the rear surface of the refractor element, and is configured to transmit an image incident thereupon along the optical path. The detector is positioned facing the rear surface of the refractor element. The diffraction grating faces the front surface of the refractor element, and is configured to spectrally disperse and reimage the image of the slit toward the front surface of the refractor element. The corrector lens is positioned between the refractor element and the diffraction grating such that the image is provided to the detector corrected for a spherical aberration caused by a separation distance between the detector and the rear surface of the refractor element.

A device for the spectral dispersion of light suitable for use in a spectrographic mode with arrays of solid state photo-detectors. Light from an entrance aperture passes through a dispersing prism with two curved, refracting surfaces both operating near their aplanatic conjugates. After being reflected by a concave mirror located behind the prism, light returns through the prism in the opposite direction, the refractions at each face again being nearly aplanatic. Spectrally dispersed images of the entrance aperture are formed on a plane well separated from the entrance aperture and nearly normal to the incident light rays. Good image quality is maintained over a broad range of operating wavelengths simultaneously, allowing large spectral intervals to be surveyed without moving any of the elements of the system.

A compact concentric-tube catalytic reaction apparatus for converting distillable hydrocarbon feedstock or methanol to useful industrial gases, such as hydrogen and carbon monoxide, comprises an annular reaction chamber concentrically disposed around an internal burner chamber. An infrared burner assembly vertically disposed within the burner chamber provides a uniformly radiating source for heat transfer to the reaction chamber. The burner chamber employs a convective section of enhanced thermal efficiency. The present invention eliminates the problems of flame impingement and local heat maldistribution associated with compact designs employing flame burners directly radiating to the reaction chamber wall.

A method of fabricating multiple layer, solid, thin films on a substrate having a surface to be coated, the method providing control over the thickness, stoichiometry, and morphology of each separate layer formed by a method comprising steps: A. forming a first ion beam from an inert gas; B, bombarding a target surface with said first ion beam in a vacuum chamber to generate a vapor cloud composed of the target material atoms by the process of sputtering; C. adjusting the respective positions of the substrate surface for coating and the target surface to promote the condensation of the vapor upon the substrate surface for coating; D. forming a second ion beam, the second ion beam's ions being formed from a mixture of inert and reactive gases; E. bombarding the substrate surface simultaneously with the second ion beam to promote a chemical reaction between the target vapor atoms and the chemically reactive gas ions as the target atoms and the chemically reactive gas ions impinge upon the substrate surface for coating, the resulting chemical compound building up in thickness as a homogeneous thin solid film layer; F. positioning an alternative target material in the place occupied by the previous one; G.

A method of fabricating a bubble domain device composite structure on a substrate of depositing a barrier layer of a suitable polymeric dielectric material on the substrate; subsequently depositing a layer of electrically conductive material thereover; subsequently depositing a spacer layer of a liquid polymeric dielectric material over the conductive layer; processing the spacer layer so that the surface of the spacer layer is substantially planar; and subsequently depositing a layer of a magnetically operative material over the spacer layer.

Aspects of the disclosure relate to correction of aberration in optical systems. In one aspect, correction of aberration can rely on a corrector lens that is movably positioned between an objective lens and an optical member, and that can introduce a perturbation to a convergent beam of light that forms an image at the substantially the focal point of the objective lens. The formed image presents aberration and such a perturbation can correct at least a portion thereof. In another aspect, the corrector lens can embody or can comprise a positive power lens, that introduces the perturbation via, at least in part, a radially symmetric wavefront correction into the convergent beam, where such a correction varies as a fourth power of a radial distance from a central axis of propagation of the convergent beam of light.
