摘要： An integrated optofluidic device to illuminate, along an irradiation direction, a fluidic sample containing an object to be analysed, the device comprising: a substrate comprising an entry surface and being made of a material transparent to a light beam incident through the entry surface along the irradiation direction; a microfluidic channel formed in the substrate and having a channel portion intercepting the irradiation direction and extending along a longitudinal axis transverse to the irradiation direction, the microfluidic channel comprising a first flow inlet port for loading a fluidic sample therein, and an elongated lens cavity for an optofluidic cylindrical lens, the cavity being formed in the substrate and being arranged along the beam irradiation direction between the entry surface and the microfluidic channel, wherein the lens cavity is in fluid communication with a lens inlet port for loading a lens fluid.
