Abstract: A compact optical test system for a chemical analyzer comprises a light-proof enclosure formed by two joined side compartments. One includes control surfaces for accurately positioning optical elements along desired light paths. The other includes retaining surfaces to maintain the optical elements in a centered position across the parting line of the two compartments. A single light source is used for both absorbance and fluorescence polarization measurement purposes.
