1. A wafer comprising an array of channels, from which wafer a plurality of optical cells can be produced each having a channel with an opening into which a sample fluid can be fed, which optical cells are suitable for use in optical analysis employing one or more wavelengths of electromagnetic radiation (EMR), and which comprise a material that is at least partially transparent to the EMR employed in the optical analysis, which channels are disposed within each cell such that a sample fluid can be fed therein, and can be irradiated with EMR directed through the at least partially transparent material, characterised by the wafer and optical cells having an inner layer and one or more outer layers, the inner layer comprising the channels of the optical cells, and one of the outer layers comprising a reflecting surface such that, when an optical cell is in use, EMR transmitted through sample fluid in the channel is reflected from the reflective surface and back through the sample fluid.
