The devices and systems disclosed herein provide multiple optical capabilities in a single device or system. Methods for using these devices and systems are provided. These devices and systems are configurable for operation in each of a spectroscopy mode, a fluorescence mode, and a luminescence mode, and are capable of performing spectroscopic, fluorescence, and luminescence observations, measurements, and analyzes when operated in the corresponding spectroscopy mode, fluorescence mode, or luminescence mode. These devices and systems include mirror dispersion elements having multiple faces including an optical dispersion element on one face (e.g., a diffraction grating or a prism) and a reflective element on another face (e.g., a mirror). These multiple capabilities eliminate the need to move or load a sample in multiple devices when subjecting a sample to multiple analyzes, and thus provide greater accuracy, precision, and speed while reducing complexity and cost of sample analysis. |
