Embodiments of a cell culture monitoring system are disclosed that may include a device having collimating and filtering components to elicit and detect fluorescence from a substrate located within a reaction vessel. The device may be used to detect changes in pH and dissolved oxygen levels in a liquid contained in the reaction vessel due to growth of living cells. Excitation light beams can be generated and collimated by a beam combiner and directed into the reaction vessel so as to be incident upon the substrate to cause the substrate to fluoresce. Some embodiments include use of expected wavelength offsets and shifted filters/mirrors to improve functionality and reduce space of device components.
