A low profile spectrometer includes one or more electromagnetic energy emitters, one or more electromagnetic energy detectors, and an optical path including a sampling element. The optical path optically couples each of the one or more electromagnetic energy emitters to one of the one or more electromagnetic energy detectors. The one or more electromagnetic energy detectors and the one or more electromagnetic energy emitters are formed on a common substrate. The spectrometer may also include one or more first re-imaging elements for optically coupling the one or more electromagnetic energy emitters to the sampling element, and one or more second re-imaging elements for optically coupling the one or more electromagnetic energy detectors to the sampling element. The sampling element is capable of being optically coupled to a sample and provides a path for optically coupling the one or more first re-imaging elements to the one or more second re-imaging elements.

A multi-spectral imaging apparatus with a common collecting aperture, which combines a high performance infrared imaging system with a high performance millimeter wave transceiving system. Two mirror surfaces are combined with a refractive corrector in the infrared mode and with a single reflective parabolic antenna in the millimeter wave mode. The dual mode system functions well in a scanning as well as a staring configuration.
