Collimating lenses use a high performance optical element (lens) manufactured using research-grade synthetic fused silica that has excellent transmission characteristics and higher operating temperatures than other elements.
  

  Collimating lenses come set to standard effective focal length distances.  However, a means of adjustment is built into the body to allow precision adjustments. 

 

  Light Couplers are devices/fiber assemblies used to channel multiple wavelengths into a single fiber.  These light couplers offer close to 50/50 coupling from each channel.  This is superior performance over standard bifurcated type fiber assemblies that can typically only provide 25% coupling efficiency from each channel.
