Abstract
A system is provided for performing filter-based and monochromator-based measurements. The system includes a light source and a plurality of detectors. An excitation monochromator outputs a selected wavelength component of the excitation light. Emitted light from a sample follows a selected emission optical path. An emission monochromator outputs a selected wavelength component of the emitted light when part of the selected path. An interface cartridge includes emission light ports positioned to direct the emitted light from the sample along a corresponding optical path. The interface cartridge aligns a selected optical path with the main measurement optical axis. A movable sliding switch mechanism provides optical channels corresponding to positions on the sliding switch mechanism to complete a selected emission optical path. The position on the sliding switch mechanism is selected by moving the sliding switch mechanism to align the optical channel for the position with the main measurement optical axis.
