  • Improved Interferometric Optical Testing
    the phase shift is independent of wavelength. Figure 2 is a schematic of a. Twyman-Green interferometer that uses the micropolarizer phase-shifting array (Proc. SPIE 5531, 304-14). Figure 3 shows the results for measuring a 300 mm diameter with a 2 meter radius of curvature, where the. mirror...
  • Medical Device Link .
    . The physical parameters of surface topography and roughness, component dimensions, radius of curvature, and coating thickness all affect the medical benefit of these devices. Device manufacturers need surface metrology tools that can simultaneously map all of these parameters for a range...
