Optofluidic prism

Light enters through a fiber from the left, traverses a silicone cube—where it is embedded in the hollow prism filled with liquid—and then exits. An optical fiber on the right collects part of the beam. Optofluidic prisms measure the refractive index of liquids. –Sergio Calixto, Centro de Investigaciones en Optica, Mexico
