  3. Application Note: Reduce Cost Of Optics And Final Assembly: The Benefits Of Laser-Reflection Based Ultra-Precision Active Alignment 1/28/2010
    Aligning and centering lenses for cementing or positioning in an optical system poses different challenges depending on the final precision requirements and the methods used during alignment. Desired quality, efficiency, cost of components and capital investment all play important roles in selecting the correct assembly method. The LASER ALIGNMENT AND ASSEMBLY STATION™ (LAS) is a dynamic laser reflection based, non-contact, real-time optical centration and angular measurement instrument, designed for aligning lenses in a multi-element optical system, such as a telescope, microscope objective or microlithography stepper. The LAS’s optical module provides strong, clear reflections by which the user can easily measure and record sub-micron Total Indicated Runout (TIR) for spheric, aspheric, parabolic, cylindric, coated, or uncoated optics with radius of curvatures from 2.0mm to infinity, without changing objectives.

  4. Negative-Stiffness Vibration Isolation Gaining Popularity As The Need For Refined Imaging With Laser/Optical Systems Increases 4/23/2009
    Laser and optical systems, whether used in academic labs or industry, are very susceptible to vibrations from the environment and these instruments frequently need vibration isolation. When measuring a very few angstroms or nanometers of displacement an absolutely stable surface has to be maintained upon which to rest the instrument. Any vibration, coupled into the mechanical structure of the instrument, will cause vertical noise and fundamentally an inability to measure these kinds of high resolution features. By Jim McMahon

  7. White Paper: Design And Characterization Of Uniform Spectral Radiance Source For Test And Calibration Of Radiometers Used For KOPMSAT-3 7/10/2008
    An application-specific uniform calibration source is described. The biggest challenge in developing the system is to achieve 25% higher spectral radiance values than the Earth’s spectral radiance, with the lowest wavelength being the hardest to meet. This pre-flight test equipment will be used for characterization and calibration of imaging radiometers which will be used as satellite-borne remote sensors for KOPMSAT-3. The integrating sphere-based system will be used as a spectral radiance standard
