Thorlabs' Liquid Light Guides (LLGs) offer outstanding transmission from 340 - 800 nm for white light illumination applications. For large core diameters, liquid light guides are a more efficient transmission solution than fiber bundles as they eliminate the packing fraction loss (dead space) that fiber bundles have. These light guides are recommended for use with tungsten halogen, xenon, or metal halide light sources and can be mounted to an optical breadboard by using one of our VH1 V-Mounts, a Ø1/2" (12.7 mm) post, and post holder. The Ø3 mm and Ø5 mm light guides can also be mounted to SM1-threaded (1.035"-40) components using the adapters sold below.

These liquid light guides are offered from stock in lengths of 4', 6', and 8' with a core diameter of either 3 or 5 mm, and their long-term temperature range is -5 to 35 °C. LLGs with custom lengths are also available as made-to-order items by contacting us.

Thorlabs also offers microscope collimation adapters for the Ø3 mm and Ø5 mm liquid light guides. These adapters allow the LLGs to be directed into the illumination ports used by various microscope manufacturers.

 

SM1 Adapter for the Liquid Light Guides

  • Designed to Mate Ø3 mm or Ø5 mm Liquid Light Guides to SM1 Standard
  • External SM1 (1.035"-40) Threading

These Liquid Light Guide Adapters allow the integration of our Ø3 mm and Ø5 mm liquid light guides into any of our selection of SM1-threaded (1.035"-40) components, such as fixed optic mounts, kinematic optic mounts, and lens tubes. The liquid light guide is secured with a nylon-tipped setscrew using a 5/64" hex key (found in the CCHK kit).

 

Collimating Microscope Adapters

 

Thorlabs offers collimation adapters with AR-coated aspheric condenser lenses (EFL = 40 mm) for collimating the output from our High Power Light Sources. Four different collimator housings are available; each is designed to mate to the illumination port on an Olympus IX/BX, Leica DMI, Nikon Eclipse, Zeiss Axioskop, or Nikon Eclipse Ti microscope.

These adapters quickly mount onto the end of either the Ø3 mm or Ø5 mm Liquid Light Guide (LLG). The LLG is secured via a setscrew into the back of the collimator. The addition of these adapters allows the user to incorporate our HPLS200 series lamps into a microscope illumination port.
