Types of Light Guides

Technology-mcob led

Both liquid light and fiber light guides exhibit their own unique attributes for the relevant curing applications.

  • Moderate cost
  • High transmission capability
  • 3, 5, and 8mm tip diameters from most manufacturers
  • Can be coupled to custom optics
  • Degrade over time
  • 2,000 – 4,000 hour life
  • Have a “shelf life”
  • Extended range version required for transmission below 300nm
  • Multi-legged versions require daily balancing
  • Economical choice for light delivery
  • More challenging to customize

Quartz Type / High Power Type

  • Up to 50% more output than standard fiber guides
  • 30% more output than bifurcated liquid guides
  • +/-5% balanced output in multi-legged light guide
  • Higher packing fraction
  • Very long life
  • Greater flexibility in curing process
  • High power transmission
  • Provides 25%- 50% more throughput allowing more energy from lamp
  • Moderate cost
  • No balancing required
  • High numerical aperture fiber that can gather 42 degrees of light as compared to 25 for a standard fiber guide
  • Do not degrade over time
  • Very durable and does not degrade over extended UV light transmission
  • Unlimited shelf life
  • Available in 1, 2, 3, and 4 legs
  • Transmits wavelength from 160-1200nm eliminating the need for extended range light guides
  • Can be coupled to custom optics
  • Easier to customize
