Abstract: The present disclosure provides an optical imaging system with adjustable magnification. In one aspect, the optical imager, which defines an optical axis, includes an object plane and an image plane, an optical sub-system located along the optical axis and optically disposed between the object plane and the image plane, the optical sub-system being configured to substantially image electromagnetic radiation emanating from the object plane onto the image plane, and at least one detecting element located substantially at the image plane. In one example, the object plane and the image plane are separated by a fixed distance. In one example, the optical sub-system is configured to mechanically translate along the optical axis.

Abstract: A spectrometer having a housing, where the housing also includes a structure located within the housing, the structure being adapted to hold a reflective dispersive element and being movable in a direction substantially perpendicular to an interior longitudinal axis. An actuator arm extends from a location exterior to the housing to another location inside the housing. The actuator arm is disposed through an opening in the housing and is operatively connected to the structure. A cryogenic actuator motor is operatively connected to the actuator arm, thereby enabling movement of the structure and the reflective dispersive element in a direction substantially perpendicular to said interior longitudinal axis, whereby alignment of the spectrometer is enabled.

Abstract: A hyperspectral imager including a first optical sub-system, at least one slit element, a second optical sub-system, at least one reflective dispersive element located at a center plane, and at least one detecting element located at substantially an image surface. During operation, the first optical sub-system images, onto the slit element(s), electromagnetic radiation originating at a source. The second optical sub-system substantially collimates, at a center plane, electromagnetic radiation emanating from the slit element(s). The second optical sub-system also images, onto the image surface, the electromagnetic radiation reflected from the reflective dispersive element(s). The detecting element(s) detect the dispersed electromagnetic radiation reflected from the reflective dispersive element(s).

Abstract: Coiled valve metal mesh of great void fraction and lengthy dimension and having a continuum of interconnected metal strands is coated with an electrocatalytic coating from liquid composition. The coating operation proceeds by contacting the mesh with liquid coating composition while the mesh is maintained in coiled form. This highly efficient coating method is continued through a curing operation while further maintaining the coated mesh in coiled form. Pretreatment preceding coating operation, e.g., degreasing and etching, may also be accomplished without uncoiling of the mesh. The coated mesh can later be uncoiled and current distributors welded to it for use as an electrode, e.g., in cathodic protection.
