• NRL Arch Reflectivity Measurement
  The NRL Arch is the industry standard for testing the reflectivity of materials. Originally designed at the Naval Research Laboratory, the NRL Arch allows for quick, repeatable non-destructive testing of microwave absorbent materials over a wide frequency range. Reflectivity is defined...

  affect critical dimension (CD) control and process yield, which inevitably eats away at a fab's profitability. Optics design is fundamental to a system's relative sensitivity to contamination. High-reflectivity systems, such as rear-view mirrors, must be. MICRO: Viewpoint...
• MICRO: Spotlight
  several x-ray techniques, including x-ray reflectivity, x-ray fluorescence, and grazing incident x-ray fluorescence. This powerful combination of techniques provides a nondestructive way to study thin films. (S.F., South Hall, Booth 2830) MicroPlanarSTI2100 for shallow-trench isolation (STI) processes...
• Spectrophotometers Measure the Color of Meat (.pdf)
  ; figure 2 shows the reflectivity spectra of meat. First, the meat is measured using the Spectrophotometer, and the spectral reflectance is sent to a computer....
• Ultrasound scans IN THIN AIR
  a defect-free region. This property permits the detailed imaging of a sample's interior features. A direct-reflection mode characterizes surfaces because reflectivity of ultrasound energy relates directly to surface roughness. Typical uses for noncontact ultrasound imaging. MATERIALS. Aircraft/aerospace...
• MICRO: Special Apps
  of the polarization state of the beam leaving the Wollaston prism after the two reflected beams have recombined. The intensity (I) as a function of time (t) is derived by the equation shown in Figure 4, where r1 and r2 represent the reflectivity of both sample sites (mask and etched feature), D...
• Fiber Optic Lever Displacement Transducers: Principles, Improvements, & Applications
  different optical lever responses and thus can be ratioed to provide an output signal directly independent of surface reflectivity.4. An unusually novel form of Fiber Optic Lever Transducer employs a pair of large diameter fibers whose axis are inclined at an angle relative to one another rather than...

  by the mirror reflectivity. Therefore,. using highly reflective astigmatic mirrors with R > 99.99% the laser beam can travel 10,000. passes, lengthening a 20cm long cavity to an optical pathlength of 2,200 meters. This allows. Off-Axis ICOS to have very high sensitivity and low detection limit 3...
• MICRO: TechEmergent
  ) from Jetalon. The CAS consists of a fully integrated, miniaturized optical reflectivity device, an optical fluidic cell, and a DSP-based electronic circuit. It uses optical reflectivity to measure refractive index and, therefore, concentrations of liquids. The optical reflectivity device includes...
• Monitoring Skin Temperature during Hand-Object Interactions
  for this system measures over the waveband of 7.5 to 13 µm. In order to. characterize the optical properties of the external optics in this spectral range, that is the contact materials. and beamsplitter, the spectral transmissivity and reflectivity of the optics were measured with a spectrometer.
