Teflon® AF Water Core Light Guide:
Excellent optical clarity and extremely low refractive index. Teflon® AF tubing forms an optical fiber when filled with virtually any transparent liquid, including water.
Teflon® AF Index of Refraction 1.29
H2O Index of Refraction 1.33
- Raman or Fluorescence
Spectroscopy: Liquid Core Teflon® AF light guide can enable up to 1000 fold intensity enhancement relative to conventional sampling methods.
- Absorbance Spectroscopy: Liquid Core Teflon® AF capillary hollow fibers can provide path lengths two to three orders of magnitude longer than those of current sample cells, enhancing sensitivity and allowing small sample volume.
