Patent ID: 8351026

Claim:
A system for acquiring one or more images of a probe array, the system comprising: a first light source configured to provide a first set of one or more excitation wavelengths, wherein a first excitation filter is configured to alter the first set of one or more excitation wavelengths, wherein the first light source is a light-emitting diode, and wherein a first lens is configured to collimate illumination from the first light source; a second light source configured to provide a second set of one or more excitation wavelengths, wherein a second excitation filter is configured to alter the second set of one or more excitation wavelengths, wherein the second light source is a light-emitting diode, and wherein a second lens is configured to collimate illumination from the second light source; a first detector configured to detect fluorescent emissions from the probe array, wherein a first emission filter is configured to allow transmission of a first set of one or more emission wavelengths to the first detector; a second detector configured to detect fluorescent emissions from the probe array, wherein a second emission filter is configured to allow transmission of a second set of one or more emission wavelengths to the second detector; and a stage configured to hold and translate the probe array within the system.
