  • Articulated Alignment Scope
    on a routine basis. Strong magnification was. ITI designed and built a 40X alignment. needed to make small parts. telescope having fiberoptic illumination. A special. visible for most accurate. articulated joint was designed in allowing the. alignment. Instrument would. scope to be folded downward
  • Optical Metrology for Large Telescope Optics
    , Tucson, AZ 85706 800-261-6640 www.4DTechnology.com. 3 of 4. A p p l i c A t i o n n o t e. Mirror Segment Alignment. The JWST project also required a method for verifying that the segments of the primary mirror, which are folded. for launch, will align to within sub-wavelength tolerance upon
  • Transit Levels
    Transit levels are used for plane surveying. These devices include transits and transit compass. A transit is an alignment telescope mounted on a tripod along with a built-in spirit level that provides a flat, level line of sight. When calibrated, a transit can indicate not only true horizontal
  • The PRIMA fringe sensor unit
    in single-mode fibres (g) by means of coupling doublets. The cold optics image the fibre bundle (f) on the four-quadrant infrared detector (d) after spectral dispersion. The fibre bundle is mounted onto a 2-axis linear piezoelectric stage for lateral image alignment, and its focus position is adjustable
  • Hubble Spots Rare Triple Eclipse on Jupiter
    At first glance, Jupiter looks like it has a mild case of the measles. Five spots - one colored white, one blue, and three black - are scattered across the upper half of the planet. Closer inspection by NASA's Hubble Space Telescope reveals that these spots are actually a rare alignment of three
  • Dynamic Interferometry: Getting Rid of the Jitters
    . during each 30-ms exposure; but the. WWW.PHOTONICSDIRECTORY.COM. H-31. Dynamic Interferometry. The challenge for this system was. achieving and maintaining subpixel. mechanical alignment between the. single-mode laser. four cameras over the entire image. This requires six degrees of freedom. phase
  • Dynamic Phase-Shifting Electronic Speckle Pattern Interferometer
    coupling to assist in the alignment of the incident polarization with the. fast or slow axis of the fiber. The field of illumination for the test beam is controlled changing the separation. between the illumination lenses. The test article is imaged onto the CCD via an imaging lens relay combination
  • Precision Refractive Zoom Lens with Long Focal Length (.pdf)
    zoom telescope using two Cassegrain telescopes. We chose an all-refractive system because of. higher throughput and ease of fabrication and assembly in addition to our confidence in maintaining alignment in a rugged. environment. We have designed and fabricated an optically-compensated refractive zoom
