Abstract: An optical assembly is disclosed comprising an elbowed optical conduit comprising a first surface, a second surface, and a third surface, wherein the third surface is configured to receive signal light from the first surface and reflect the signal light towards the second surface; a first laterally variable bandpass optical filter optically coupled to the second surface and configured to receive the signal light propagated in the elbowed optical conduit; a second laterally variable bandpass optical filter arranged at a distance from the first laterally variable bandpass optical filter; and a sensor coupled to the second laterally variable bandpass optical filter; wherein the first laterally variable bandpass optical filter has a first bandpass center wavelength; and wherein the second laterally variable bandpass optical filter has a second bandpass center wavelength.

Abstract: There is described a flow spectrometer optical assembly (60) comprising:
a light source (61) configured to provide illuminating light (53);
a cuvette comprising a cavity (65) configured to receive and contain a sample (51) while transmitting the illuminating light through the cell;
an optical assembly (20) that includes an optical filter; and
a sensor (43), coupled to the optical filter, configured to selectively detect signal light (23) propagated through the optical filter,
wherein the signal light (23) is emitted by the sample (25) in fluid form while the sample in fluid form is in the cavity (65).
