Sigma Fiber Optics, Inc.

 

 

Specializing in fused glass capillary arrays

Glass capillaries arrays are used as matrices for spatially imaging radiation detectors when filled with scintillating liquids or crystals. Depending on the scintillator material used these detectors are capable of detecting x-rays, gamma rays, fast neutrons or other high energy particles.

These capillary arrays serve as both the containing matrix and the optical cladding for the scintillating material, which acts as the optical core for the fiber-optic light collection and light channeling within the array. The light generated within the scintillator is guided to the end faces of the array where it can be read out by appropriate image amplification techniques.

Capillary arrays are available in a variety of sizes and specifications:

  • Pore sizes from 1 mm to 20 microns *
  • Array cross-sections from 0.1 to 100 cm2 *
  • Array thickness (lengths) from 1 cm to 30 cm *
  • Refractive index of array glass: 1.49
  • Open area ratio of array: 0.8 - 0.9
  • Arrays can be furnished with EMA (stray light absorber).
  • Basic array structure is close-packed hexagonal.
  • Arrays are fused all-glass structures (not cemented with organic resins).
  • Arrays are essentially chemically inert
  • Expansion coefficient: approx. 50x10-7 /C°
  • Stable at temperatures up to 500 C°
  • Arrays are very light weight but structurally rugged.
  • Arrays are also available in round form with a surrounding glass tube for additional ruggedness.
  • Array faces are furnished diamond-cut flat.

  * Not all combinations are available

We also manufacture single capillaries of various sizes and glass types.
