Abstract:
An apparatus for optically interrogating a reaction mixture contained in a reaction vessel having a chamber for holding the mixture, the apparatus comprising:a) a first optics assembly comprising: i) at least two light sources for transmitting excitation beams to the chamber; ii) a first set of filters for filtering the excitation beams such that each of the beams transmitted to the chamber has a substantially distinct excitation wavelength range; and iii) a first housing for holding the light sources and the first set of filters, wherein the light sources and the first set of filters are rigidly fixed in the first housing; and b) a second optics assembly comprising: i) at least two detectors for detecting light emitted from the chamber in at least two respective emission wavelength ranges; ii) a second set of filters for separating the light emitted from the chamber into the respective emission wavelength ranges; and iii) a second housing for holding the detectors and the second set of filters, wherein the detectors and the second set of filters are rigidly fixed in the second housing.
