Abstract
Systems and methods are disclosed herein for measuring a fundamental mode vibrational spectrum of materials and substances in the Mid-IR spectral range of 2.5 μm to 14 μm wavelength. In one embodiment, a Mid-infrared FT-IR spectrometer system measures, identifies, or quantifies substances in the spectral range 2.5 μm to 14 μm. The system includes an infrared Micro-Electro-Mechanical System (MEMS) single element emitter light source. The light source is configured in operation to be electrically pulsed and to emit electromagnetic radiation in the wavelength range from 2.5 μm to 14 μm and with integral energy concentrating optic to provide energy for a spectral absorption process. A scanning beam splitter is positioned in an interferometer optical path with fixed angle mirrors and a thermal detector having a sensitivity to determine a maximum optical sensitivity of the system.
