Abstract
The multi-channel fluorescence detection device includes an illumination module, plural heating chambers, a detection module and a transmission module. The illumination module includes at least one light source, plural different types of excitation filters, and a first rotational drum, wherein the light source provides a broad band illumination, each of the excitation filters passes light at a particular band width for exciting a targeted fluorescent probe, and the first rotational drum drives the excitation filters. The plural heating chambers are adapted for accommodating PCR tubes having samples and the targeted fluorescent probes. The detection module includes plural different types of emission filters, a second rotational drum and at least one photo-detector, wherein each of the emission filters passes light at a particular band width, the second rotational drum drives the emission filters, and the photo-detector receives fluorescent signals and converts the fluorescent signals to electrical signals. The transmission module includes an actuator connecting with the first and the second rotational drums to drive rotations of the first and the second rotational drum simultaneousl…
