Our systems can be equipped with double monochromators on either or both excitation and emission arms. The use of double monochromators increases the linear dispersion, and stray light suppression is improved over that achieved by single monochromators to give better signal to noise ratios. A double monochromator in the emission arm allows for up to three detectors mounted simultaneously with software-based selection; two detectors can be fitted after the double monochromator and one after the first of the two monochromators.
If further detectors are required, the system can be configured in a T-geometry by the addition of a separate emission monochromator. This configuration can also be useful to provide a digital detection arm and an analogue detection arm.
