FIS Matching Gel helps to reduce optical loss within fiber optic mechanical splices and connectors, apply optical couplant at the interface of the two mated fibers. This minimizes loss by reducing the difference in the index of refraction between the mated fibers. 

Features
• Very High Clarity
• Good mechanical shear stability
• Low bleed and evaporation
• Excellent adhesion
• Reduce internal reflection and refraction in optical instruments（Optical cameras、Gamma cameras、Scintillators、Fiber Optics）
