Abstract
A light guide device for transmitting light through a column of light transmitting medium and into an adjacent culture growing solution, including a barrier structure for separating the medium and solution, the barrier structure being light transmissive to allow for extraction of light and being adapted to hold a material of reduced refractive index relative to the medium so as to provide total internal reflection for light incident the barrier structure at greater than a critical angle to thereby guide the light through the device.

A light guide device for transmitting light including a barrier structure with first and second walls for separating a column of light transmitting medium and a culture solution;
- wherein the first and second walls are separated by a gap;
- and wherein the first and second walls are light transmissive to allow light to be extracted from the medium, into the culture solution.
