Abstract

Usually optofluidic lenses are spherical (ball lenses), plano - concave or plano - convex. Here we present a method to fabricate non - ball small microfluidic lenses in the bulk of a polymer. The cavity of these lenses can be filled with a liquid by means of a syringe. Liquids present different refractive index thus the lens focal distance can be changed at will. An optical characterization study and an application in the measurements of liquids refractive index are shown. Arrays of microfluidic lenses were also fabricated.
