Abstract:
1. A system for providing multiple wavelengths of light to a probe array, comprising: a source to alternately tune an excitation light to a first wavelength within an excitation range of a first fluorescent label associated with a first target molecule, and a second wavelength within an excitation range of a second fluorescent label associated with a second target molecule, wherein the source alternates between tuning the excitation light to the first and second wavelengths in succession; one or more optical elements to direct the excitation light comprising the first wavelength and the excitation light comprising the second wavelength to at least one pixel position associated with the probe array; and a detector to detect a third wavelength of light emitted in response to the first wavelength and a fourth wavelength of light emitted in response to the second wavelength.
