Collimating Lenses


  • Used to Focus or Collimate a Light Beam
  • Available in Two Diameters: 6 mm and 12.7 mm
  • Standard UNS 1/4”-36 for SM connection
  • Adjustable SMA Connector
    Achieving uniform illumination of a sample using optical fibers requires the use of collimating lenses, curved optical lenses that convert a divergent beam into a parallel beam. For this to occur, the light-emitting source must be placed at the focus of the lens. On the other hand, if the light collected is already collimated, the lens will work as a focusing lens. 

    Collimating lenses offered by Sarspec are optimized for the UV-Vis-NIR range and allow users to adjust the field of view, control spatial resolution, and illumination and collection efficiency.Available in a smaller 6-mm and larger 12.7-mm diameter, our collecting lenses have a two-part anodized aluminum housing with an inner barrel threaded for SMA-905 connectors that helps you to adjust the focal point.
