Abstract
Systems and methods for biological sample detection by combining and directing light with an optical blender that provides a composite beam from spatially and spectrally distinct non-parallel light sources.
Claims20
A biological sample excitation system, the system comprising:
- a first light source emitting a first light beam having a first optical spectrum;
- a second light source spatially separated from the first light source, the second light source emitting a second light beam having a second optical spectrum, wherein the second optical spectrum is different from the first optical spectrum, and wherein the first light beam and the second light beam have non-parallel paths;
- and
- an optical blender positioned in the paths of the first light beam and the second light beam, wherein the optical blender combines the first light beam and the second light beam into a composite beam directed toward a luminescent dye that produces emission light in relation to nucleic acid present in the biological sample.
