  • Application of X-ray Mask Fabrication Technologies to High Resolution, Large Diameter Ta Fresnel Zone Plates
    The resolution of Fresnel zone plate (FZP) as X-ray lens is determined by the width of outer-most zone, and the diameter of condenser lens is desirable to be large so that bright x-ray beam is available in x-ray optical systems. As the diameter of FZPs with nm resolution reported so far is small
  • Cut the Lights
    John Null, is in microcomputer programming and in the Fresnel lens beaming room light to the infrared sensor. The Fresnel lens is a special design that has both vertical and horizontal elements. Room light passes through it onto a two-element IR detector. "We've refined the detection technique
