Liquid light guides (LLG) provide flexible and convenient conduits for light delivery to fluorescence microscopes and other bioanalytical instruments. In addition to isolating the microscope from any heat and vibration associated with the light source, passage through a light guide acts to randomize spatial inhomogeneity in the light source output.
One disadvantage, however is that up to 30% of the original source output can be lost in the process of coupling into, and transmission through, the light guide. We have recently modified the design of our liquid light guides to minimize these losses. The result is liquid light guides that deliver about 10% more output to the microscope than their predecessors.
