ABSTRACT:
An optical detection and orientation device is provided comprising a housing having an excitation light source, an optical element for reflecting the excitation light to an aspherical lens and transmitting light emitted by a fluorophore excited by said excitation light, a focusing lens for focusing the emitted light onto the entry of an optical fiber, which serves as a confocal aperture, and a moveable carrier for accurately moving said housing over a small area in relation to a channel in a microfluidic device. The optical detection and orientation device finds use in detecting fluorophores in the channel during operations involving fluorescent signals.
