Abstract
The invention relates to a plurality of light sources to power a variety of applications including microarray readers, microplate scanners, microfluidic analyzers, sensors, sequencers, Q-PCR and a host of other bioanalytical tools that drive today's commercial, academic and clinical biotech labs.
Claims15
A method for analyzing a sample comprising:
- (a) pumping excitation light from one or more photo luminescent light pipes together with excitation light from one or more light emitting diodes using one or more dichroic mirrors that produces a single coaxial beam;
- (b) directing the beam of excitation light onto the sample;
- and
- (c) directing light from the sample onto one or more detectors.
1 more element
A solid-state light engine adapted to analyze a sample having one or more tags comprising:
- at least one light pipe;
- a plurality of solid state light source;
- one or more dichroic mirrors;
- wherein at least one of the solid state light source drives the luminescence in the light pipe;
- and
- wherein the at least one light pipe, the plurality of solid state light sources, and the one or more dichroic mirrors are used to produce a single beam of excitation light having a plurality of colors;
- wherein the beam of excitation light is adapted to selectively detect the one of more tags within the sample.
4 more elements
A system adapted to analyze a sample having one or more tags comprising:
- a light pipe and at least one solid state light source that drives luminescence in the light pipe;
- an additional one or more solid state light sources;
- a plurality of dichroic mirrors;
- wherein said light pipe and said at least one solid state light source, said additional one or more solid state light sources, and said plurality of dichroic mirrors are used to produce a single beam of excitation light having a plurality of colors, wherein the beam of excitation light is adapted to detect the one or more fluorescent tags within the sample;
- at least one filter that filters the beam of excitation light;
- and
- an optical delivery pipe that is adapted to direct the beam of excitation light from onto a sample.
