Abstract
The present invention relates to a device for the detection of a fluorescent dye in a sample, comprising a radiation source with the aid of which light for exciting the fluorescent dye to be detected can be transmitted into the sample applied to a carrier, and a detecting device for detecting fluorescent light which has been emitted by the fluorescent dye to be detected. The present invention is characterized by a hollow space having an internal high-reflectance surface, a first aperture directed towards the sample, and a second aperture located opposite the detecting device.
Claims24
A device for the detection of a fluorescent dye in a sample, said device comprising
- a radiation source configured to transmit light to excite the fluorescent dye to be detected into the sample applied to a carrier,
- a detector configured to detect fluorescent light from the fluorescent dye to be detected,
- a hollow space having an internal high-reflectance surface, a first aperture directed towards the sample, and a second aperture located opposite the detector, and
- a dichroic beam divider configured to direct part of the light emitted by the radiation source onto the sample and to conduct part of the fluorescent light emitted by the fluorescent dye to be detected into the hollow space.
A device for the detection of a fluorescent dye in a sample, said device comprising
- a radiation source configured to transmit light to excite the fluorescent dye to be detected into the sample applied to a carrier,
- a detector configured to detect fluorescent light from the fluorescent dye to be detected,
- a hollow space having an internal;
- high-reflectance surface, a first aperture directed towards the sample, and a second aperture located opposite the detector, and
- a blocking filter in front of the first aperture of the hollow space, the blocking filter opaque to the excitation light and transmissive to the fluorescent light to be detected.
A device for the detection of a fluorescent dye in a sample, said device comprising
- a radiation source configured to transmit light to excite the fluorescent dye to be detected into the sample applied to a carrier,
- a detector configured to detect fluorescent light from the fluorescent dye to be detected, and
- a hollow space having an internal high-reflectance surface, a first aperture directed towards the sample, and a second aperture located opposite the detector,
- wherein the radiation source and the carrier have provided between them a scanner configured to guide rays emitted by the radiation source over the carrier, and further
- wherein said scanner comprises a focusing lens configured to focus the rays emitted by the radiation source onto the sample, and said focusing lens comprises an F/θ lens.
