Abstract：A novel micro infrared spectrometer was designed which is different from traditional grating scanning one. This micro spectrometer introduced an uncooled infrared detector LiTaO3 with high sensitivity and small volume, and a MEMS pulsed infrared light source was adopted as emitter and chopper, which threw off traditional mechanical chopper. Combined with the design of a two-double light route, the volume of micro spectrometer was made even smaller. Primary results show that the design method of micro-infrared spectrometer is feasible, the wavelength range of instrument is wide, from 2 000 to 5 000 nm, and spectrum bandwidth is about 45 nm, which can be used for the sample analysis, such as plastic films, biologic liquid, environmental gas and so on.
