Abstract:
An apparatus for differentiating multiple detectable signals comprises a light source (16) that can emit respective excitation light wavelengths toward a sample in a sample retaining region (10).
Abstract:
An instrument may include an array of sample wells, a plurality of samples arranged in the array of sample wells, a plurality of light sources, a plurality of detectors, a plurality of lightpipes arranged between the plurality of samples and the plurality of detectors, and a plurality of lightpipes arranges between the plurality of light sources and the plurality of detectors. The samples include a plurality of detectable markers being capable of generating increased emission due to a presence of a target component in the sample. The detectable markers have a respective excitation wavelength range and a respective emission wavelength range. The light sources are capable of emitting a plurality of excitation wavelength ranges toward the plurality of samples to respectively excite the detectable markers. The detectors are capable of detecting an emission wavelength range emitted from the detectable markers.
Abstract:
An optical instrument is provided for simultaneously illuminating two or more spaced-apart reaction regions with an excitation beam generated by a light source. A collimating lens can be disposed along a beam path between the light source and the reaction regions to form bundles of collimated excitation beams, wherein each bundle corresponds to a respective reaction region. Methods of analysis using the optical instrument are also pro vided.
