Abstract: An optical sensor for multispectral analysis of a fluid sample comprises at least one light source, at least one interference filter, and a plurality of light detectors arranged such that light emitted by the at least one light source is incident on the at least one interference filter. There is a spatial variation in the intensity of light incident on the said at least one interference filter.
