A modified evanescent-wave fiber-optic fluorometer capable of simultaneous signal enhancement and suppression of stray excitation light is examined. Such a capability is achieved by adjusting the shape of a fluorophore sample droplet and regulating the distance separating the exit of the illuminating fiber and an uncladded segment of the receiving fiber, set perpendicular to each other. The effects of sample attenuation and inhomogeneity are also analyzed and evidenced by associated experiments.
