Patent Number: 
Section: claims

1. A method of manufacturing X-ray lenses comprising the steps of: a) providing a layer of liquid on a flat surface of a first substrate,  b) arranging a plurality of pipe-shaped lens components in a row following an axis which extends parallel to said flat surface in said layer of liquid; and  c) holding said pipe-shaped lens components between a flat surface of a second substrate and the flat surface of said first substrate, such that said liquid fills in spaces formed by an exterior surface of said pipe-shaped lens components and the flat surface of said first substrate or the flat surface of said second substrate. 2. The method of  claim 1 , in which the pipe-shaped lens components are carbon nanotubes. claim 1 3. The method of  claim 1 , in which the liquid is silicon grease having a viscosity reduced by addition of a solvent. claim 1 4. An X-ray lens comprising: a) a plurality of pipe-shaped lens components which transmit X-rays,  b) a liquid which holds said pipe-shaped lens components and  c) a pair of substrates for holding said liquid and said plurality of pipe-shaped lens components, each having a flat surface facing said pipe-shaped lens components, and said pipe-shaped lens components are lined up following a same direction. 5. The X-ray lens of  claim 4 , wherein said pipe-shaped lens components are carbon nanotubes. claim 4 6. The X-ray lens of  claim 4 , in which the liquid is silicon grease having a viscosity reduced by addition of a solvent. claim 4
