Abstract: An exemplary optical limiter device (100) has an optically transmissive substrate (102) and a layer (104) on a first surface (106) of the substrate, the layer having a trimetallic nitride endohedral metallofullerene. The layer can be a thin film of the trimetallic nitride endohedral metallofullerene, a layer material with a cavity containing a solution with the trimetallic nitride endohedral metallofullerene, a sol-gel with a trimetallic nitride endohedral metallofullerene, and a self assembled monolayer with a trimetallic nitride endohedral metallofullerene. The layers of trimetallic nitride endohedral metallofullerenes can be vapor deposited, solution deposited and/or self assembled onto optical components. The third-order nonlinear properties of these films provide desired transmission characteristics.

Abstract: A device and method for measuring optical properties of a sample are provided. The device comprises a housing surrounding a flow-through flow-cell. The flow-cell has a sample inlet positioned proximate to a first end of the flow-cell and a sample outlet positioned proximate to a second end of the flow-cell. A sample chamber is positioned between the sample inlet and the sample outlet. A plurality of excitation sources are positioned on the housing in an operable relationship to the sample chamber. At least one excitation source has a wavelength that is different from the other excitation sources. Each excitation source is incident on a sample in the flow-cell. At least one fluorescence emission detector is positioned in an operable relationship to the flow-cell. The fluorescence emission detector detects a continuous broadband spectrum of emission wavelengths emitted from the sample upon excitation by each excitation source.

Abstract: The positioning of image data written along a laser beam scan path in the scan direction, e.g., the margin and/or line length is adjusted in a manner that compensates for changes in the laser beam scan path as a result of one or more operating conditions, such as changes in temperature. Further, the positioning of image data in the process direction may be adjusted in a manner that compensates for changes in the laser beam scan path as a result of the one or more operating conditions.

Abstract: A scanning apparatus for a printer or similar instrument. A multiharmonic oscillator is used to provide a composite motion of a laser beam or other light beam to scan an imaging surface. The multiharmonic oscillator may have multiple sections each having a different resonant frequency. One section includes a reflector that intercepts the light beam, and drive electronics move the reflector so the light beam scans the imaging surface. Linear and complex non-linear motions of the light beam may be achieved. Microelectromechanical systems (MEMS) technology may be used to fabricate the oscillator.
