Light Guides

FTI produces thousands of different fiber optic cable configurations in glass, plastic, and silica (quartz) fiber for all markets we serve.

FTI glass and plastic light guide designs for industrial applications and Machine Vision Optics
Typical single and bifurcated light guide

Standard products have the following features:

  • Your choice of fiber type:
    • “Plastic” fiber used for the best color rendition and the brightest white light. (.55 NA)
    • “Glass” fiber used in fiber optic cables and light guides for best results with solid state silicon IR emitters and detectors. .55 or .66 NA typical, other NAs available)
    • Silica fiber typically used when the target spectrum is outside the visible range. (.22 or .37NA)
  • Stainless steel construction:
    • The flexible jacketing and all end fittings are made from 300 series stainless steel for maximum fiber protection and long, trouble free service.
  • 300 degree C epoxy. (Typical)
  • Ceramic high temperature epoxy enables each end to be usable up to 1100°F continuously.
  • Swaged end fittings create secure connection to the sheathing.
  • Machine polishing on all fiber faces ensures the best light output in the industry.
  • Standard Lengths: 1,2,3,4,5,6,8,10,20,30 Feet. (.3,.6,.9,1.2,1.5,1.8,3,6,9M)

Options

Have a special application? You may change the length, sheathing material, bundle diameter and fiber type. You may also specify custom fittings for either or both ends. Any light guide may have the fibers randomized for optimal uniformity.

Finally, high heat, vacuum or pressure applications can be produced, but require special consideration.
