Disclosed are methods and apparatus adapted to aid in an illumination of a test sample in a test vessel. The method includes sequencing multiple wavelength light sources by turning OFF all but the light source of interest and taking a reading. The illumination apparatus has a bracket with a first and second arms and a space between them adapted to receive a test vessel, an array of light sources and a lens array coupled to the first arm, an array of bandpass filters adapted to filter light signals from each light source, at least one aperture array adapted to limit an extent of light emitted to the test vessel, and a single photo detector coupled to the second arm adapted to receive light signals from each of the light sources without moving the test vessel. Systems are disclosed, as are other aspects. |
